English subject–verb agreement looks simple until a sentence contains more than one noun.
- The key to the cabinets is missing.
- The keys to the cabinet are missing.
The verb agrees with the grammatical subject, not automatically with the nearest noun. Yet speakers and writers sometimes produce forms such as The key to the cabinets are missing because the plural noun cabinets sits close to the verb.
This error tendency is called agreement attraction.
English also contains cases where meaning legitimately influences agreement. A collective noun such as team may take singular or plural agreement in different varieties and contexts depending on whether the group is treated as one unit or as multiple members. This is notional agreement.
Together, these phenomena reveal that agreement is not a single mechanical rule. It emerges from grammatical structure, number features, lexical convention, proximity, meaning, discourse and variety.
For the wider architecture, begin with How English Works and the English Learning Hub. This route connects especially to Constituent Structure, Quantification and Scope, and Determiner Systems and Reference.
The shortest useful definition
Agreement attraction is the tendency for an intervening or nearby noun to influence verb agreement even though it is not the true grammatical controller. Notional agreement occurs when agreement follows conceptual number rather than surface grammatical number alone.
Compare:
- The list of names is on the desk. — grammatical agreement with singular list.
- The list of names are on the desk. — attraction error in standard formal English.
- The team is winning. — group treated as one unit.
- The team are arguing among themselves. — plural notional agreement, especially natural in British English.
The first contrast is an error pattern. The second can reflect legitimate variation in how a group is conceptualised.
Agreement is structural, not merely linear
In The key to the cabinets is missing, the subject noun phrase is:
[The key [to the cabinets]]
The head of the noun phrase is key. The phrase to the cabinets modifies the head but does not control ordinary subject–verb agreement.
A reliable agreement system must therefore identify hierarchical structure before looking at number.
This is why “agree with the nearest noun” is not a general rule of English.
The classic attraction configuration
Agreement attraction becomes especially likely when the true subject and an intervening noun have different number features.
- The key to the cabinets is…
- The report on the experiments shows…
- The quality of the materials has improved.
The plural attractor can interfere with production because it is more recent in working memory than the singular head.
Psycholinguistic research uses these sentences to study how speakers compute agreement in real time. The error is revealing precisely because fluent speakers usually know the underlying rule but can still be pulled toward the wrong number under processing pressure.
Why attraction happens
Several mechanisms can contribute:
- the attractor noun is linearly close to the verb;
- its plural marking is highly visible;
- the subject noun phrase is long or structurally complex;
- the true head has faded in working memory;
- semantic plurality makes the plural reading conceptually tempting.
Agreement attraction is therefore a window into the interface between grammar and processing.
Singular heads with plural attractors are especially risky
A classic asymmetry is that singular-head/plural-attractor sentences often trigger more errors than plural-head/singular-attractor sentences.
- The key to the cabinets… — vulnerable.
- The keys to the cabinet… — generally less vulnerable.
One explanation is that plural is a more marked feature in English. The visible plural attractor can intrude strongly into the agreement calculation.
Students do not need the psycholinguistic theory to edit accurately, but the pattern explains why certain mistakes feel surprisingly persistent.
Prepositional phrases hide attractors
- The box of old photographs is upstairs.
- The effect of the new rules remains unclear.
- The reliability of these measurements has improved.
The nouns inside of-phrases are especially common attractors because they sit between the subject head and verb.
A quick editing method is to temporarily remove the interrupting phrase: The box is, The effect remains, The reliability has.
Once the head–verb relation is visible, agreement becomes easier.
Relative clauses can create distance
Relative clauses can separate the subject head from the matrix verb:
The student who completed the three experiments is presenting today.
The plural noun experiments belongs inside the relative clause. It does not control the matrix verb is.
This requires readers to track clause boundaries rather than allowing the nearest plural noun to dominate.
See Relative Clauses and Information Attachment.
Notional agreement: meaning can legitimately matter
Not every departure from simple singular-form/singular-verb matching is an error.
Collective nouns can refer either to a group as one entity or to its members as individuals.
- The committee has reached a decision. — one institutional unit.
- The committee are divided in their opinions. — members acting separately; especially natural in British English.
American English generally favours singular agreement with many collective nouns more strongly than British English does, though context and noun type matter.
Variety therefore forms part of the agreement system.
Collective nouns create conceptual number
- team
- government
- family
- staff
- committee
- audience
Each can denote one organised unit or many individual members. The grammatical noun may be morphologically singular while the conceptual referent is plural.
Notional agreement is the language’s way of letting conceptual construal influence number marking.
Agreement should remain internally coherent
If a writer chooses singular agreement for a collective noun, later pronouns should generally fit that construal:
The committee has reached its decision.
If the group is construed as individuals:
The committee are returning to their seats.
Mixing singular and plural randomly can make the conceptual model unstable.
A number of versus the number of
This pair is one of the clearest examples of meaning controlling agreement.
- A number of students are absent.
- The number of students is increasing.
A number of behaves much like several or many; the conceptual subject is the plural set of students.
The number of refers to one quantity—the number itself—so singular agreement is standard.
The nearby noun students is identical in both sentences. The determiner structure changes the grammatical and semantic head.
A lot of, plenty of and lots of
Quantity expressions can take agreement from the noun that follows:
- A lot of water is missing.
- A lot of students are absent.
- Plenty of time is available.
- Plenty of options are available.
The surface quantifier phrase does not behave like an ordinary singular head such as lot in every construction. Contemporary agreement follows the notional and grammatical number of the quantified substance or set.
Percentages and fractions
Agreement with percentages and fractions often depends on the noun being quantified.
- Fifty per cent of the students are present.
- Fifty per cent of the water is gone.
- Two-thirds of the building is damaged.
- Two-thirds of the rooms are damaged.
The percentage itself is not inherently singular or plural. The quantified referent determines the conceptual number.
This connects agreement to quantification rather than simple morphology.
Amounts can be conceptually singular
Plural-looking measures can take singular agreement when treated as one amount:
- Ten dollars is enough.
- Five kilometres is too far to walk.
- Three hours is a long wait.
Conceptually, each phrase denotes one price, distance or duration.
But if the same units are treated as separate entities, plural agreement can return: Those five kilometres are the hardest part of the route.
Meaning determines the count structure.
Titles and named works are often singular
A title can look plural but refer to one work:
Great Expectations is a novel by Charles Dickens.
The internal noun is plural, but the whole title names one book.
This is another case where referential number outranks surface morphology.
Plural-looking singular nouns
- mathematics is fascinating
- news is spreading quickly
- physics is difficult
These nouns end in -s but are grammatically singular in their ordinary meanings.
Visual morphology can therefore attract an incorrect plural verb if a learner treats final -s as the only number cue.
Singular-looking plural nouns
- people are
- police are in ordinary British/international usage
- cattle are
Number is a lexical property, not always visible through a simple suffix.
Agreement therefore requires lexical knowledge as well as syntax.
There is / there are and proximity pressure
Existential constructions create special agreement behaviour:
- There is one problem.
- There are two problems.
Formal edited English commonly matches the verb to the following noun phrase. Conversational English, however, widely uses contracted there’s before plural phrases: There’s two people outside.
This is not ordinary attraction from a subject head because existential there has a special clause architecture. See Existential There.
Either…or and neither…nor use proximity in many styles
Correlative subjects create another special case:
- Either the teachers or the principal is attending.
- Either the principal or the teachers are attending.
Many edited-English conventions use proximity agreement here, though variation exists and mixed-number pairings can sound awkward.
This is a legitimate construction-specific rule, not the same thing as accidental attraction. See Correlative Coordination.
None can be singular or plural
None historically relates to “not one,” but modern standard English permits both singular and plural agreement depending on meaning and following noun.
- None of the water is left.
- None of the students are ready.
Plural agreement is well established when none refers to no members of a plural set.
A rigid rule that none must always be singular does not describe contemporary standard English adequately.
Data, media and other changing nouns
Some nouns shift agreement conventions over time and across disciplines.
Data is historically plural from Latin datum, and plural agreement remains common in some scientific styles: The data are consistent. In general contemporary English, mass-noun singular agreement—The data is consistent—is also widespread.
Media similarly has historical plural morphology but can function as a collective or mass-like noun in some modern contexts.
Writers should match disciplinary convention and maintain internal consistency rather than assuming etymology alone settles present usage.
Agreement in relative clauses with one of
Sentences such as the following are structurally demanding:
She is one of the students who work hardest.
Under the standard analysis, who refers to students, so the relative-clause verb is plural.
Compare:
She is the one student who works hardest.
The difference depends on the antecedent of the relative pronoun, not merely which noun sits closest.
Agreement errors often reveal parsing errors
When a writer produces the wrong verb number, the deeper problem may be that the noun phrase has been parsed incorrectly.
The purpose of the new procedures are… often means the writer has temporarily treated procedures as the subject because it is closer to the verb.
Correcting agreement therefore begins by reconstructing constituent structure, not by staring harder at the verb.
Agreement in academic writing
Academic sentences frequently contain long noun phrases, making attraction especially dangerous:
The effect of repeated changes in reporting requirements has not been measured.
The true head is effect. The plural nouns changes and requirements are embedded inside modifiers.
A useful editing technique is to bracket the full subject and underline its head before checking the verb.
Agreement in journalism
News writing frequently handles organisations and collective institutions:
The government has announced… versus The government have announced…
Both patterns can occur in standard English depending on national variety and whether the institution is construed as one body or multiple members.
Publication style should therefore define an internal house convention while remaining aware of legitimate external variation.
Agreement in spoken English
Speech is produced incrementally under time pressure, so attraction and proximity effects are especially understandable.
A speaker may begin The problem with all these rules… and then select are because rules is the most recent plural noun.
Self-repair can then restore the intended agreement. Listening comprehension usually tolerates such slips because the semantic structure remains recoverable.
Edited writing, however, gives the writer time to resolve them.
A compact agreement map
| Pattern | Agreement principle | Example |
|---|---|---|
| head + modifier | head controls | The key to the rooms is… |
| collective noun | grammar + notional number + variety | The team is/are… |
| a number of | plural set | A number of students are… |
| the number of | singular quantity | The number of students is… |
| percentage/fraction | number of quantified noun | Half the water is / half the students are |
| measure as one amount | notional singular | Ten dollars is enough |
| either/or | construction-specific proximity often used | Either X or the students are… |
Common learner errors
- Making the verb agree with the nearest noun inside an of-phrase.
- Failing to identify the head of a long subject noun phrase.
- Treating every collective noun as obligatorily singular or obligatorily plural.
- Confusing a number of with the number of.
- Assuming plural-looking measurements always require plural verbs.
- Using etymology alone to decide contested modern nouns such as data.
- Applying ordinary nearest-noun reasoning to special constructions such as either…or.
A practical method for students
- Bracket the entire subject. Where does it begin and end?
- Find the head noun. Which noun determines the phrase’s core identity?
- Ignore embedded attractors temporarily. Remove of-phrases and relative clauses mentally.
- Check special quantity constructions. A number of, percentages, fractions, measures?
- Check notional number. Is a collective being treated as one unit or multiple members?
- Check variety and style. Does the publication convention prefer singular or plural collective agreement?
- Restore the full sentence. Confirm that agreement still fits once modifiers return.
Why agreement attraction and notional agreement belong inside How English Works
Agreement attraction reveals that grammatical knowledge and real-time processing are not identical. Speakers can know which noun controls agreement while still being pulled toward a nearby plural under cognitive pressure.
Notional agreement reveals the opposite lesson: sometimes meaning genuinely matters more than surface form. A team can be one unit or many members; ten dollars can be ten individual dollars or one total amount.
English agreement is therefore a negotiation among syntax, lexical number, conceptual number, construction type and discourse convention.
Teaching Guide
Teach agreement by making students locate the subject head before they look at the verb. Use sentences such as The key to the cabinets is missing and physically bracket the modifier to the cabinets. Then remove the bracketed material so the head–verb relation becomes obvious.
Next, introduce genuine notional agreement. Compare The committee has reached its decision with The committee are arguing among themselves, then discuss dialect and publication style. This prevents students from treating every non-singular collective pattern as an error.
Finish with quantity constructions: a number of, the number of, percentages, fractions and measurements. Mastery means knowing when to resist a nearby noun and when the meaning of the whole expression legitimately controls agreement.
