Complement clauses in translation are the clauses and non-finite phrases that complete the meaning of another verb, adjective or noun. English says She said that the test was difficult, She wants to leave, She wants him to leave, She enjoys reading and She stopped reading. These constructions can look similar on the page while assigning different participants, time relations and event structures. A translation that chooses the wrong complement form can quietly change who acts, whether an event happened, or whether a speaker reports, wants, remembers or causes something.
People searching for how to translate that-clauses, infinitives, gerunds, control verbs, raising constructions, verb complements or non-finite clauses are solving a predicate-complement problem. Languages differ in whether they prefer finite subordinate clauses, infinitives, gerunds, verbal nouns, participles or serial constructions. They also differ in how they mark the subject of the embedded action. Precise translation therefore treats the matrix verb and its complement pattern as one meaning structure rather than translating the main verb first and improvising the rest.
This article owns the complement-clause precision layer. It explains finite that-clauses, infinitival complements, gerund complements, subject control, object control, raising, perception complements, causative complements, factive and non-factive predicates, complementizer omission and ambiguity. It also provides diagnostics for deciding who performs the embedded action and whether the complement refers to an event, proposition, possibility, intention or completed fact. The central rule is: identify the matrix predicate, embedded proposition and embedded subject before choosing the target construction.
Finite That-Clauses
The key is to identify the source relation before choosing target syntax. A finite complement such as ‘she believes that the plan will work’ packages a proposition as the content of believing. In practice, this means separating the source into its functional parts before drafting. The target may use a different complementizer, non-finite form, aspectual verb, path expression, question particle or clause order. That is acceptable only when the same participant roles, event boundaries, discourse assumptions and task demands remain recoverable to the target reader.
The common failure is turning the embedded proposition into a separate main assertion or losing the reporting/attitude frame. This can survive ordinary proofreading because every individual target word may be grammatical and plausible. The error appears only when the reviewer asks what event completed, who controls the embedded action, what path the mover follows, or what information the question actually requests. In technical, educational, legal, research and professional contexts, such a shift can alter instructions, claims, chronology, responsibility or required responses.
A practical method is to label matrix predicate and embedded proposition separately For example, BELIEVE [plan will work] keeps the plan claim inside the believer’s mental state. Before release, ask whose commitment the target expresses. This converts intuition into a repeatable check. When the source leaves something ambiguous or underspecified, preserve or flag that uncertainty instead of forcing a neat target interpretation. The goal is not to keep the source grammar visible; it is to keep the source relation intact.
Complementizer Omission
A precise translation treats this as a semantic-and-grammatical mapping problem. English can omit that in many contexts without changing the basic complement relation. In practice, this means separating the source into its functional parts before drafting. The target may use a different complementizer, non-finite form, aspectual verb, path expression, question particle or clause order. That is acceptable only when the same participant roles, event boundaries, discourse assumptions and task demands remain recoverable to the target reader.
The common failure is assuming the absence of that means two independent clauses. This can survive ordinary proofreading because every individual target word may be grammatical and plausible. The error appears only when the reviewer asks what event completed, who controls the embedded action, what path the mover follows, or what information the question actually requests. In technical, educational, legal, research and professional contexts, such a shift can alter instructions, claims, chronology, responsibility or required responses.
A practical method is to test whether the second clause answers what was said, thought, known or believed For example, “She said the test was easy” still contains a complement clause. Before release, target should preserve embedding even if its language requires an overt marker. This converts intuition into a repeatable check. When the source leaves something ambiguous or underspecified, preserve or flag that uncertainty instead of forcing a neat target interpretation. The goal is not to keep the source grammar visible; it is to keep the source relation intact.
Infinitival Complements
This becomes difficult when the target language packages the same meaning through a different construction. To-infinitives can express intended, controlled, expected or future-like events depending on the governing predicate. In practice, this means separating the source into its functional parts before drafting. The target may use a different complementizer, non-finite form, aspectual verb, path expression, question particle or clause order. That is acceptable only when the same participant roles, event boundaries, discourse assumptions and task demands remain recoverable to the target reader.
The common failure is treating all infinitives as generic future clauses. This can survive ordinary proofreading because every individual target word may be grammatical and plausible. The error appears only when the reviewer asks what event completed, who controls the embedded action, what path the mover follows, or what information the question actually requests. In technical, educational, legal, research and professional contexts, such a shift can alter instructions, claims, chronology, responsibility or required responses.
A practical method is to identify the semantic relation of the matrix verb For example, “hope to leave,” “decide to leave” and “manage to leave” differ in intention, decision and successful completion. Before release, check event status and subject reference. This converts intuition into a repeatable check. When the source leaves something ambiguous or underspecified, preserve or flag that uncertainty instead of forcing a neat target interpretation. The goal is not to keep the source grammar visible; it is to keep the source relation intact.
Subject Control
The source wording is only the surface; the underlying event or clause relation is the invariant. In subject-control constructions, the matrix subject is also understood as the embedded subject. In practice, this means separating the source into its functional parts before drafting. The target may use a different complementizer, non-finite form, aspectual verb, path expression, question particle or clause order. That is acceptable only when the same participant roles, event boundaries, discourse assumptions and task demands remain recoverable to the target reader.
The common failure is assigning the embedded action to another participant. This can survive ordinary proofreading because every individual target word may be grammatical and plausible. The error appears only when the reviewer asks what event completed, who controls the embedded action, what path the mover follows, or what information the question actually requests. In technical, educational, legal, research and professional contexts, such a shift can alter instructions, claims, chronology, responsibility or required responses.
A practical method is to expand the silent subject privately For example, “Lina promised to leave” normally means Lina will leave. Before release, state explicitly who performs the infinitive. This converts intuition into a repeatable check. When the source leaves something ambiguous or underspecified, preserve or flag that uncertainty instead of forcing a neat target interpretation. The goal is not to keep the source grammar visible; it is to keep the source relation intact.
Object Control
A fluent target can still be wrong if this relation changes during restructuring. In object-control constructions, the matrix object controls the embedded action. In practice, this means separating the source into its functional parts before drafting. The target may use a different complementizer, non-finite form, aspectual verb, path expression, question particle or clause order. That is acceptable only when the same participant roles, event boundaries, discourse assumptions and task demands remain recoverable to the target reader.
The common failure is making the matrix subject perform the infinitive. This can survive ordinary proofreading because every individual target word may be grammatical and plausible. The error appears only when the reviewer asks what event completed, who controls the embedded action, what path the mover follows, or what information the question actually requests. In technical, educational, legal, research and professional contexts, such a shift can alter instructions, claims, chronology, responsibility or required responses.
A practical method is to name the embedded subject after the matrix object For example, “Lina persuaded Omar to leave” means Omar leaves. Before release, compare actor roles source-target. This converts intuition into a repeatable check. When the source leaves something ambiguous or underspecified, preserve or flag that uncertainty instead of forcing a neat target interpretation. The goal is not to keep the source grammar visible; it is to keep the source relation intact.
Promise vs Persuade
The key is to identify the source relation before choosing target syntax. Near-similar sentence patterns can differ radically in control structure. In practice, this means separating the source into its functional parts before drafting. The target may use a different complementizer, non-finite form, aspectual verb, path expression, question particle or clause order. That is acceptable only when the same participant roles, event boundaries, discourse assumptions and task demands remain recoverable to the target reader.
The common failure is translating by surface order instead of verb-specific frame. This can survive ordinary proofreading because every individual target word may be grammatical and plausible. The error appears only when the reviewer asks what event completed, who controls the embedded action, what path the mover follows, or what information the question actually requests. In technical, educational, legal, research and professional contexts, such a shift can alter instructions, claims, chronology, responsibility or required responses.
A practical method is to learn matrix verb together with complement pattern For example, “Lina promised Omar to leave” points to Lina; “Lina persuaded Omar to leave” points to Omar. Before release, ask who is expected to leave. This converts intuition into a repeatable check. When the source leaves something ambiguous or underspecified, preserve or flag that uncertainty instead of forcing a neat target interpretation. The goal is not to keep the source grammar visible; it is to keep the source relation intact.
Raising Constructions
A precise translation treats this as a semantic-and-grammatical mapping problem. Raising verbs and adjectives do not assign a semantic role to the surface subject in the same way control verbs do. In practice, this means separating the source into its functional parts before drafting. The target may use a different complementizer, non-finite form, aspectual verb, path expression, question particle or clause order. That is acceptable only when the same participant roles, event boundaries, discourse assumptions and task demands remain recoverable to the target reader.
The common failure is treating a raised subject as intentional actor. This can survive ordinary proofreading because every individual target word may be grammatical and plausible. The error appears only when the reviewer asks what event completed, who controls the embedded action, what path the mover follows, or what information the question actually requests. In technical, educational, legal, research and professional contexts, such a shift can alter instructions, claims, chronology, responsibility or required responses.
A practical method is to paraphrase with an impersonal proposition For example, “Lina seems to understand” ≈ “It seems that Lina understands.” Before release, check whether matrix predicate describes Lina’s action or the proposition’s appearance. This converts intuition into a repeatable check. When the source leaves something ambiguous or underspecified, preserve or flag that uncertainty instead of forcing a neat target interpretation. The goal is not to keep the source grammar visible; it is to keep the source relation intact.
Raising-to-Object Patterns
This becomes difficult when the target language packages the same meaning through a different construction. Some constructions make an embedded subject look like a matrix object. In practice, this means separating the source into its functional parts before drafting. The target may use a different complementizer, non-finite form, aspectual verb, path expression, question particle or clause order. That is acceptable only when the same participant roles, event boundaries, discourse assumptions and task demands remain recoverable to the target reader.
The common failure is assigning matrix-verb patient role where none exists. This can survive ordinary proofreading because every individual target word may be grammatical and plausible. The error appears only when the reviewer asks what event completed, who controls the embedded action, what path the mover follows, or what information the question actually requests. In technical, educational, legal, research and professional contexts, such a shift can alter instructions, claims, chronology, responsibility or required responses.
A practical method is to recover the underlying embedded proposition For example, “We believe Lina to be ready” ≈ “We believe that Lina is ready.” Before release, preserve belief content rather than action on Lina. This converts intuition into a repeatable check. When the source leaves something ambiguous or underspecified, preserve or flag that uncertainty instead of forcing a neat target interpretation. The goal is not to keep the source grammar visible; it is to keep the source relation intact.
Gerund Complements
The source wording is only the surface; the underlying event or clause relation is the invariant. -ing complements can denote activities, events or propositions selected by a matrix verb. In practice, this means separating the source into its functional parts before drafting. The target may use a different complementizer, non-finite form, aspectual verb, path expression, question particle or clause order. That is acceptable only when the same participant roles, event boundaries, discourse assumptions and task demands remain recoverable to the target reader.
The common failure is translating them as ordinary nouns and losing event structure. This can survive ordinary proofreading because every individual target word may be grammatical and plausible. The error appears only when the reviewer asks what event completed, who controls the embedded action, what path the mover follows, or what information the question actually requests. In technical, educational, legal, research and professional contexts, such a shift can alter instructions, claims, chronology, responsibility or required responses.
A practical method is to identify the event and participant For example, “She enjoys reading” describes enjoyment of the activity of reading. Before release, target should preserve activity relation. This converts intuition into a repeatable check. When the source leaves something ambiguous or underspecified, preserve or flag that uncertainty instead of forcing a neat target interpretation. The goal is not to keep the source grammar visible; it is to keep the source relation intact.
Stop + Gerund vs Stop + Infinitive
A fluent target can still be wrong if this relation changes during restructuring. English distinguishes cessation of an activity from pausing one action in order to perform another. In practice, this means separating the source into its functional parts before drafting. The target may use a different complementizer, non-finite form, aspectual verb, path expression, question particle or clause order. That is acceptable only when the same participant roles, event boundaries, discourse assumptions and task demands remain recoverable to the target reader.
The common failure is collapsing both constructions. This can survive ordinary proofreading because every individual target word may be grammatical and plausible. The error appears only when the reviewer asks what event completed, who controls the embedded action, what path the mover follows, or what information the question actually requests. In technical, educational, legal, research and professional contexts, such a shift can alter instructions, claims, chronology, responsibility or required responses.
A practical method is to paraphrase each event sequence For example, “She stopped smoking” = ceased smoking; “She stopped to smoke” = stopped another activity in order to smoke. Before release, draw timeline of events. This converts intuition into a repeatable check. When the source leaves something ambiguous or underspecified, preserve or flag that uncertainty instead of forcing a neat target interpretation. The goal is not to keep the source grammar visible; it is to keep the source relation intact.
Remember + Gerund vs Remember + Infinitive
The key is to identify the source relation before choosing target syntax. Complement form can change whether memory concerns a past event or a future task. In practice, this means separating the source into its functional parts before drafting. The target may use a different complementizer, non-finite form, aspectual verb, path expression, question particle or clause order. That is acceptable only when the same participant roles, event boundaries, discourse assumptions and task demands remain recoverable to the target reader.
The common failure is preserving the verb remember while reversing event time. This can survive ordinary proofreading because every individual target word may be grammatical and plausible. The error appears only when the reviewer asks what event completed, who controls the embedded action, what path the mover follows, or what information the question actually requests. In technical, educational, legal, research and professional contexts, such a shift can alter instructions, claims, chronology, responsibility or required responses.
A practical method is to mark whether embedded action occurred before or after remembering For example, “remember locking the door” recalls past locking; “remember to lock” means do not forget future task. Before release, compare timeline. This converts intuition into a repeatable check. When the source leaves something ambiguous or underspecified, preserve or flag that uncertainty instead of forcing a neat target interpretation. The goal is not to keep the source grammar visible; it is to keep the source relation intact.
Try + Gerund vs Try + Infinitive
A precise translation treats this as a semantic-and-grammatical mapping problem. Try can mean experiment with a method or attempt an action. In practice, this means separating the source into its functional parts before drafting. The target may use a different complementizer, non-finite form, aspectual verb, path expression, question particle or clause order. That is acceptable only when the same participant roles, event boundaries, discourse assumptions and task demands remain recoverable to the target reader.
The common failure is flattening experimental versus effortful meanings. This can survive ordinary proofreading because every individual target word may be grammatical and plausible. The error appears only when the reviewer asks what event completed, who controls the embedded action, what path the mover follows, or what information the question actually requests. In technical, educational, legal, research and professional contexts, such a shift can alter instructions, claims, chronology, responsibility or required responses.
A practical method is to paraphrase as ‘experiment with X’ or ‘attempt X’ For example, “try restarting” suggests a possible solution; “try to restart” emphasizes attempt. Before release, check pragmatic purpose. This converts intuition into a repeatable check. When the source leaves something ambiguous or underspecified, preserve or flag that uncertainty instead of forcing a neat target interpretation. The goal is not to keep the source grammar visible; it is to keep the source relation intact.
Factive Complements
This becomes difficult when the target language packages the same meaning through a different construction. Some matrix predicates presuppose or present the complement as true. In practice, this means separating the source into its functional parts before drafting. The target may use a different complementizer, non-finite form, aspectual verb, path expression, question particle or clause order. That is acceptable only when the same participant roles, event boundaries, discourse assumptions and task demands remain recoverable to the target reader.
The common failure is translating factive content as mere belief or possibility. This can survive ordinary proofreading because every individual target word may be grammatical and plausible. The error appears only when the reviewer asks what event completed, who controls the embedded action, what path the mover follows, or what information the question actually requests. In technical, educational, legal, research and professional contexts, such a shift can alter instructions, claims, chronology, responsibility or required responses.
A practical method is to test with negation and complement status For example, “She regrets that the meeting ended” normally treats the ending as fact. Before release, preserve embedded commitment. This converts intuition into a repeatable check. When the source leaves something ambiguous or underspecified, preserve or flag that uncertainty instead of forcing a neat target interpretation. The goal is not to keep the source grammar visible; it is to keep the source relation intact.
Non-Factive Attitude Complements
The source wording is only the surface; the underlying event or clause relation is the invariant. Believe, hope and suspect do not automatically establish the complement as fact. In practice, this means separating the source into its functional parts before drafting. The target may use a different complementizer, non-finite form, aspectual verb, path expression, question particle or clause order. That is acceptable only when the same participant roles, event boundaries, discourse assumptions and task demands remain recoverable to the target reader.
The common failure is making the target assert the embedded proposition directly. This can survive ordinary proofreading because every individual target word may be grammatical and plausible. The error appears only when the reviewer asks what event completed, who controls the embedded action, what path the mover follows, or what information the question actually requests. In technical, educational, legal, research and professional contexts, such a shift can alter instructions, claims, chronology, responsibility or required responses.
A practical method is to keep the complement inside the attitude frame For example, “They suspect the data are incomplete” does not establish incompleteness. Before release, ask whether the narrator endorses the claim. This converts intuition into a repeatable check. When the source leaves something ambiguous or underspecified, preserve or flag that uncertainty instead of forcing a neat target interpretation. The goal is not to keep the source grammar visible; it is to keep the source relation intact.
Perception Complements
A fluent target can still be wrong if this relation changes during restructuring. See/hear can take bare infinitives, -ing clauses or finite complements with different aspectual perspectives. In practice, this means separating the source into its functional parts before drafting. The target may use a different complementizer, non-finite form, aspectual verb, path expression, question particle or clause order. That is acceptable only when the same participant roles, event boundaries, discourse assumptions and task demands remain recoverable to the target reader.
The common failure is losing whether the perceiver witnessed a whole event or ongoing activity. This can survive ordinary proofreading because every individual target word may be grammatical and plausible. The error appears only when the reviewer asks what event completed, who controls the embedded action, what path the mover follows, or what information the question actually requests. In technical, educational, legal, research and professional contexts, such a shift can alter instructions, claims, chronology, responsibility or required responses.
A practical method is to identify event completeness and sensory access For example, “I saw him cross the road” presents the event as bounded; “saw him crossing” presents ongoing activity. Before release, compare aspectual viewpoint. This converts intuition into a repeatable check. When the source leaves something ambiguous or underspecified, preserve or flag that uncertainty instead of forcing a neat target interpretation. The goal is not to keep the source grammar visible; it is to keep the source relation intact.
Causative Complements
The key is to identify the source relation before choosing target syntax. Make, let, have and get combine a matrix causer with embedded action. In practice, this means separating the source into its functional parts before drafting. The target may use a different complementizer, non-finite form, aspectual verb, path expression, question particle or clause order. That is acceptable only when the same participant roles, event boundaries, discourse assumptions and task demands remain recoverable to the target reader.
The common failure is confusing who causes and who acts. This can survive ordinary proofreading because every individual target word may be grammatical and plausible. The error appears only when the reviewer asks what event completed, who controls the embedded action, what path the mover follows, or what information the question actually requests. In technical, educational, legal, research and professional contexts, such a shift can alter instructions, claims, chronology, responsibility or required responses.
A practical method is to map causer, embedded actor and result For example, “She made Omar leave” means she caused Omar’s leaving. Before release, compare role table. This converts intuition into a repeatable check. When the source leaves something ambiguous or underspecified, preserve or flag that uncertainty instead of forcing a neat target interpretation. The goal is not to keep the source grammar visible; it is to keep the source relation intact.
Adjective Complements
A precise translation treats this as a semantic-and-grammatical mapping problem. Adjectives can select clauses or infinitives that express evaluation, certainty or readiness. In practice, this means separating the source into its functional parts before drafting. The target may use a different complementizer, non-finite form, aspectual verb, path expression, question particle or clause order. That is acceptable only when the same participant roles, event boundaries, discourse assumptions and task demands remain recoverable to the target reader.
The common failure is changing who experiences the adjective or who performs embedded action. This can survive ordinary proofreading because every individual target word may be grammatical and plausible. The error appears only when the reviewer asks what event completed, who controls the embedded action, what path the mover follows, or what information the question actually requests. In technical, educational, legal, research and professional contexts, such a shift can alter instructions, claims, chronology, responsibility or required responses.
A practical method is to identify adjective holder and embedded subject For example, “Lina is ready to leave” makes Lina ready and Lina the leaver. Before release, check both roles. This converts intuition into a repeatable check. When the source leaves something ambiguous or underspecified, preserve or flag that uncertainty instead of forcing a neat target interpretation. The goal is not to keep the source grammar visible; it is to keep the source relation intact.
Noun Complement Clauses
This becomes difficult when the target language packages the same meaning through a different construction. Nouns such as claim, fact, idea and possibility can be completed by clauses. In practice, this means separating the source into its functional parts before drafting. The target may use a different complementizer, non-finite form, aspectual verb, path expression, question particle or clause order. That is acceptable only when the same participant roles, event boundaries, discourse assumptions and task demands remain recoverable to the target reader.
The common failure is treating the clause as a relative modifier rather than content. This can survive ordinary proofreading because every individual target word may be grammatical and plausible. The error appears only when the reviewer asks what event completed, who controls the embedded action, what path the mover follows, or what information the question actually requests. In technical, educational, legal, research and professional contexts, such a shift can alter instructions, claims, chronology, responsibility or required responses.
A practical method is to ask whether the clause tells what the noun consists of/content For example, “the claim that the system failed” gives the content of the claim. Before release, separate claim-content from source assertion. This converts intuition into a repeatable check. When the source leaves something ambiguous or underspecified, preserve or flag that uncertainty instead of forcing a neat target interpretation. The goal is not to keep the source grammar visible; it is to keep the source relation intact.
Complement Choice and Meaning
The source wording is only the surface; the underlying event or clause relation is the invariant. One matrix verb can select different complements that shift event interpretation. In practice, this means separating the source into its functional parts before drafting. The target may use a different complementizer, non-finite form, aspectual verb, path expression, question particle or clause order. That is acceptable only when the same participant roles, event boundaries, discourse assumptions and task demands remain recoverable to the target reader.
The common failure is choosing target complement by grammar alone. This can survive ordinary proofreading because every individual target word may be grammatical and plausible. The error appears only when the reviewer asks what event completed, who controls the embedded action, what path the mover follows, or what information the question actually requests. In technical, educational, legal, research and professional contexts, such a shift can alter instructions, claims, chronology, responsibility or required responses.
A practical method is to compare all target options for event status and participant roles For example, regret doing, regret to inform, begin doing/to do differ in conventional use. Before release, test with timeline and speech act. This converts intuition into a repeatable check. When the source leaves something ambiguous or underspecified, preserve or flag that uncertainty instead of forcing a neat target interpretation. The goal is not to keep the source grammar visible; it is to keep the source relation intact.
Complement-Clause QA
A fluent target can still be wrong if this relation changes during restructuring. Every complement should be checked for matrix predicate, embedded subject, event status and commitment. In practice, this means separating the source into its functional parts before drafting. The target may use a different complementizer, non-finite form, aspectual verb, path expression, question particle or clause order. That is acceptable only when the same participant roles, event boundaries, discourse assumptions and task demands remain recoverable to the target reader.
The common failure is reviewing only local word choice. This can survive ordinary proofreading because every individual target word may be grammatical and plausible. The error appears only when the reviewer asks what event completed, who controls the embedded action, what path the mover follows, or what information the question actually requests. In technical, educational, legal, research and professional contexts, such a shift can alter instructions, claims, chronology, responsibility or required responses.
A practical method is to make a four-column map MATRIX / COMPLEMENT / SUBJECT / STATUS For example, promise / to leave / Lina / intended future action. Before release, source-target maps should match. This converts intuition into a repeatable check. When the source leaves something ambiguous or underspecified, preserve or flag that uncertainty instead of forcing a neat target interpretation. The goal is not to keep the source grammar visible; it is to keep the source relation intact.
Worked Examples
Worked Example 1: Promise vs Persuade
Source A: Lina promised Omar to leave early. The embedded leaver is Lina. Source B: Lina persuaded Omar to leave early. The embedded leaver is Omar. A target language may use finite clauses for both, but the embedded subject must not swap.
Recovery begins by writing the embedded clause explicitly: Lina leaves / Omar leaves. Only then choose the target complement structure. This single test catches a high-value class of role errors.
Worked Example 2: Remember Doing vs Remember to Do
Source A: Remember locking the door. The speaker refers to memory of a past event. Source B: Remember to lock the door. The speaker directs future action.
A target with one generic ‘remember + door’ structure can reverse chronology. Draw the sequence: lock→remember for A; remember→lock for B.
Worked Example 3: See Cross vs See Crossing
I saw Omar cross the road presents the crossing as a bounded observed event. I saw Omar crossing the road places the observer inside the ongoing event.
Not every language encodes this contrast with infinitive versus participle. The target can use aspect, adverbs or clause structure, but should preserve the source viewpoint when relevant.
Worked Example 4: Claim That vs Fact That
The claim that the system failed packages failure as claim content. The fact that the system failed presents failure as factive background.
If the target uses the same noun or structure for both, epistemic responsibility changes. Translate the complement and the head noun as one unit.
Practical Diagnostic Workflow
Start by underlining the matrix predicate. Bracket the complement. Write the understood subject of the embedded action and mark whether the complement is finite, infinitival, gerundial or nominal. Then record event status: asserted fact, belief content, desired event, attempted event, completed event, remembered past event, future task or perceived activity. This map is more important than preserving the source complement form.
After drafting, reverse the analysis on the target. Ask who performs every embedded action, whether the matrix predicate still controls the same participant, and whether a completed event has become merely intended or vice versa. If the target language has a completely different complement system, that is fine; the role-and-status map should still match.
Recovery When Meaning Has Drifted
When a complement error appears, remove the target non-finite or subordinate clause and reconstruct its full proposition. Then restore the matrix relation explicitly. This prevents local grammar fixes from preserving the wrong underlying actor or event status.
After repair, inspect tense, modality and pronouns in neighbouring clauses. Complement changes often propagate because the target may need different agreement, reference or temporal sequencing once the embedded subject is corrected.

Frequently Asked Questions
Should infinitives always stay infinitives?
No. Many languages use finite clauses, verbal nouns or other constructions. Preserve event relation and subject reference, not English form.
What is control?
A relationship in which a matrix participant is understood as the subject of an embedded non-finite action.
What is raising?
A construction in which a surface subject originates semantically in the embedded clause; the matrix predicate comments on the proposition rather than assigning an ordinary actor role.
Why are gerunds difficult?
Because -ing forms can be events, activities, nouns or participles, and target languages divide those functions differently.
Can complement choice change time?
Yes. Remember doing vs remember to do is a classic example; other verbs can similarly shift event status.
Can AI swap embedded subjects?
Yes, especially with control verbs and long sentences. Explicit subject mapping is a reliable check.
Where This Fits in the eduKate Translation Architecture
Use Verb Valency and Argument Structure for predicate frames, the modality article for embedded commitment, the passive/agency article for role mapping, and the existing sentence-structure owner for broad word-order reconstruction.
Final Principle
Translate complement clauses by preserving the matrix predicate, embedded proposition, embedded subject and event status. The target can change infinitives into finite clauses or gerunds into verbs; what cannot change is who does what, when it happens, and how the matrix predicate frames that event.
