How to Translate Venn Diagrams and Overlapping Sets

How to translate a Venn diagram accurately means preserving which items belong to which groups, which groups overlap, and what the shaded or numbered regions actually represent. A diagram with two circles may look simple, but a small change from “and” to “or,” from “some” to “all,” or from inclusive to exclusive language can reverse its claim.

If you are translating a Venn diagram, set-relationship graphic, classroom comparison chart or overlapping-category infographic into another language, start with the membership rules. Translate the category labels only after checking the intersections, complements, totals, exceptions and the meaning of any shaded area. The goal is not to reproduce the drawing decoratively; it is to preserve a reader’s ability to decide what belongs where.

This article explains the language and reasoning behind accurate Venn-diagram translation. It distinguishes formal mathematical sets from looser conceptual overlap diagrams, shows how to keep values tied to the correct regions, and provides a method for checking accessible text explanations. For general chart translation, eduKateSG has related articles; this guide focuses on the special problem of intersecting categories and the logic of membership.

Begin with the question the diagram is supposed to answer

Venn diagrams appear in school mathematics, biology, literature, market research, software permissions, public policy and everyday explanations. In mathematics they can represent sets precisely; in a classroom poster they might simply show what two stories have in common. In both cases, the shape is only useful if the categories mean something specific. A label such as “readers” could mean people who read any book, people who read a particular book, or respondents who selected reading as one of their hobbies. Those are not interchangeable groups.

Read the heading, instructions, legend and source note together. “People who chose A,” “people who chose only A,” and “people who did not choose B” define different regions. A translation that smooths each into “A group” hides the distinction. Before rewriting the diagram, answer three questions: what is the universe of possible items, how does each set admit a member, and what evidence supports the given counts or examples?

A strong translator can express the diagram as plain membership statements. For instance, “Everyone in the central region belongs to both A and B,” or “The outer rectangle represents all respondents to this question.” If those statements cannot be formed confidently from the source, the content requires clarification before translation. Linguistic fluency does not rescue an undefined membership rule.

Separate mathematical Venn diagrams from decorative comparison graphics

A formal Venn diagram represents logical possibilities of intersections among sets; in its standard sense, regions correspond to combinations of set membership, even if some are empty. Other overlapping-circle graphics are often called Venn diagrams in ordinary speech but may be closer to Euler diagrams, where the shape can directly indicate inclusion, exclusion or an empty overlap. A translator does not have to correct every casual classroom label, but should not add mathematical claims that the original never made.

Consider two overlapping circles marked “fiction” and “history,” with “historical novels” written in the overlap. That may be a teaching illustration rather than a fully specified classification of every book. It does not prove that historical novels are the only books that count as both. A polished translation should preserve the pedagogical purpose without turning the illustration into an exhaustive taxonomy.

Likewise, a marketing slide with two circles, “useful” and “affordable,” and an overlap labelled “our product,” is making a promotional comparison, not a measured set claim. Translate the labels and relationship, but do not lend scientific authority to the diagram by inventing population totals or universal categories. Knowing the genre determines how literal the logic should be.

State the universe before discussing complements

The complement of a set depends on what counts as the universe. “Not in A” has no fixed meaning until you know whether the diagram concerns a class of thirty students, all customers in one survey or every resident of a city. A shaded area outside a circle but inside the rectangle might represent people who did not choose A among respondents. It does not automatically represent everyone in the world who does not meet A.

Look for a rectangle, border, heading or footnote that defines the population. Preserve that scope in target-language wording. Instead of writing “all non-readers,” use “respondents who did not select reading” when the source is a survey question. This avoids converting a limited sample result into a universal social claim. It also preserves the difference between missing observations and negative responses.

If the diagram has no explicit universe, do not invent a population simply to make the explanation sound complete. Use conditional phrasing or request clarification: “Within the people represented in this chart, the region outside A …” For accessible descriptions, mention the universe early because screen-reader users cannot infer it from the enclosing rectangle alone.

Translate intersection as membership in both groups

The overlap A ∩ B includes elements that belong to A and to B. English “both” often conveys the right relationship, but the target language may use a conjunction, particle, compound form or explicit clause. The essential test is simple: could an item enter the intersection if it satisfied A but not B? If yes, your translated sentence is wrong. An intersection requires both conditions at the same time.

In a survey, respondents who chose “cycling” and “walking” belong to the intersection. They may also have chosen other activities; the overlap does not imply they chose exactly two activities unless the survey says so. “Both” is not the same as “only both.” A translation that adds “only” could exclude people who also selected swimming, even though they belong in the intersection of cycling and walking.

If a diagram shows three sets, an overlap between A and B may include the central A ∩ B ∩ C region. Some shaded diagrams intentionally exclude that centre to mean A and B but not C. Check the shading before writing the category description. The distinction between an inclusive pairwise intersection and an exclusive region becomes increasingly important as more sets are added.

Understand inclusive OR, exclusive OR and ordinary language

In formal set language, A ∪ B means items in A or B or both. Everyday languages often use “or” ambiguously: it can mean either option including both, or one option excluding the other. Translate the union so readers can tell which sense is intended. If the target phrase could mean “choose exactly one,” add a short clarification such as “one or both categories” when the original relation is an inclusive union.

Exclusive OR corresponds to membership in A or B but not both, often represented by the symmetric difference A △ B. A Venn diagram may shade the two outer crescents while leaving the intersection unshaded. Writing “A or B” without the exclusivity note can overcount. Conversely, describing a union as “A but not B, or B but not A” improperly removes the overlap.

Be especially careful with public forms, eligibility illustrations and classroom questions. “Eligible if condition A or condition B” is a real-world rule whose meaning may depend on the policy text, not on a translator’s intuition about English “or.” Preserve the authoritative definition and seek review if a diagram contradicts the written rule. Visual shorthand should not overrule a controlling document.

Keep only, at least one, exactly one and neither distinct

These phrases determine regions. “Only A” means membership in A and not B when there are exactly two relevant sets. “At least one” means the union. “Exactly one” means the exclusive parts. “Neither” means outside both sets but inside the defined universe. A translator can easily erase those differences while trying to shorten a label that must fit in a small part of a circle.

Work with elementary logical tests. Take a hypothetical person in the overlap and ask whether your translated instruction includes or excludes that person. Take another person outside both circles and run the same test. If the source and target yield different answers for either case, the translation has changed meaning. For three sets, test all eight possible membership patterns rather than only three obvious corners.

This is also a useful language-learning lesson: tiny determiners and adverbs alter mathematical truth. “Some,” “all,” “none,” “only,” “at least” and “exactly” should be treated as constraints. A sentence can be grammatically elegant and mathematically false when one of those words is moved or dropped.

Preserve subset, proper subset and disjoint relationships

One circle entirely inside another may represent A ⊆ B: every member of A is also a member of B. It does not follow that every member of B belongs to A. If the source explicitly marks a proper subset, A ⊂ B under the notation convention it defines, then B contains at least one element that is not in A. Since symbols for subset versus proper subset are used differently in some materials, rely on the source’s defined notation rather than assuming a universal typographic convention.

Two non-overlapping circles within a universe often represent disjoint sets: no element belongs to both. That does not mean the categories have no conceptual relationship in ordinary life, nor does it prove anything beyond the model’s chosen population and definitions. Translating “mutually exclusive categories” into “unrelated categories” would lose the precise sense of non-overlapping membership.

A translator should keep directionality visible in subset statements. “All sparrows in this chart are birds” does not mean “all birds are sparrows.” It is often worth using a full sentence rather than a compressed label when the target audience is learning the topic for the first time. Precise prose can be short without being cryptic.

Do not let category labels quietly change the sets

The category label determines which items qualify for membership. Suppose the source says “people who have visited the museum” but the target reads “people who like the museum.” Those may overlap, but they are not the same set. The mistake can remain hidden if the numbers still add up beautifully. Label fidelity therefore matters before arithmetic checking.

Pay attention to tense and time boundaries. “Have participated” describes an experience up to a reference point, while “will participate” describes a future plan. “Adults who work remotely at least once a week” is narrower than “adults who have ever worked remotely.” Replace neither with simply “remote workers” unless the intended meaning is preserved in a visible key. The same issue arises with thresholds: “more than five” excludes five, while “five or more” includes it.

Different cultures may categorise kinship, occupations, learning levels and social roles differently. Where a source-defined category lacks a one-word target equivalent, write a descriptive definition rather than forcing a near synonym. A Venn diagram can only be translated accurately if its membership criteria cross the language boundary intact.

Follow numbers into the correct regions

A two-circle Venn diagram may show three numbers inside the circles and one outside. These are counts tied to mutually exclusive regions, not simply labels of circle totals. If the overlap contains 8, the A-only region 12 and the B-only region 5, the total in A is 20, the total in B is 13, and the union is 25. Moving the label 8 from the intersection to one outer crescent changes every interpretation, even if no digit is mistranslated.

Do not confuse a region count with a set total. Some diagrams write “A = 20” near the top of a circle as the total and show region counts separately. Others put the count 20 inside the exclusive A region. Read instructions and placement together; when ambiguous, request the data table behind the chart. In a translated caption, explicitly say “A only,” “B only,” “both,” and “neither” rather than repeating isolated numbers.

Check units. A diagram may measure people, responses, households, books, incidents or percentages. “8 responses” is not necessarily “8 respondents” when participants could give multiple answers. Verify whether the source asks one question with multiple possible selections or several independent binary questions. Translating the units incorrectly can make a valid calculation meaningless.

Recalculate totals without silently repairing source errors

Arithmetic is an excellent review tool. In a two-set universe, A-only plus both plus B-only plus neither should equal the universe total when the regions are exhaustive and mutually exclusive. If they do not, note the discrepancy. But a translator is not licensed to alter the printed figures silently. The source may have a transcription error, a missing category, weighted percentages or a deliberately incomplete example.

For three sets, the seven internal regions plus the outside region similarly account for every membership combination in the defined universe. That is a property of the partition when the model is exhaustive, not a claim about the real world outside the chart. An unlabelled blank region may mean zero, may mean unknown or may be irrelevant. Do not convert blanks to zeros without confirmation.

If the diagram gives circle totals and intersection counts, avoid double-counting the overlap when computing the union. For example, |A ∪ B| = |A| + |B| − |A ∩ B|. A translator need not display that formula in every piece of content, but understanding it reveals when a label has migrated. Checking logic is part of translation quality assurance whenever visual placement carries meaning.

Interpret three-circle diagrams with special care

Three sets create eight membership patterns, including membership in none. Their central intersection contains items in all three. The lenses between pairs may represent membership in two sets only, or a pairwise overlap that also contains the centre, depending on the shading and notation. “A and B” by itself is inclusive of C; “A and B but not C” is a different region. Do not mix those forms while simplifying an explanation.

A common reading mistake is to look at the A-B lens and forget that the central portion also belongs to A ∩ B. If a classroom question asks “How many belong to A and B?”, it might require summing the pair-only region and the three-way intersection. If it asks “How many belong to A and B only?”, the centre is excluded. The translation must protect this contrast.

For accessible text, name regions consistently. One method is a membership code: A-only, B-only, C-only, AB-only, AC-only, BC-only, ABC, neither. Explain these codes in ordinary language before using them. Such a register also helps check that a right-to-left layout change has not moved numbers into the wrong overlap.

Separate observed membership from theoretical possibility

Some Venn diagrams represent all logically possible combinations, even when one region contains no observed items. Others show actual data only. An empty intersection could mean it is impossible for the categories to overlap, or simply that nobody in the measured sample occupied that region. Those statements differ. Translation must preserve whether zero is empirical, definitional or hypothetical.

Suppose no survey respondent selected both activities. That does not establish the activities are incompatible. A caption saying “no respondents in this sample chose both” is better than “no one can do both.” Similarly, if two biological classifications are defined to exclude one another, the empty overlap follows from the definitions rather than the accident of the sample. Readers need to know which basis supports the emptiness.

The same caution applies to percentage diagrams. A shaded region may describe a probability event rather than counted individuals. Translate “probability of A and B” as such, not as a claim that a fixed number of people belong to both groups. Units, definitions and evidence status prevent accidental overgeneralisation.

Manage labels that expand in the target language

A small central intersection may have almost no room for a long translated phrase. Instead of trimming the logic away, move the label outside with a leader line, use a short unambiguous identifier or give the definition in an adjacent textual key. An abbreviation is acceptable only if a reader can recover its meaning without already knowing the source language. The space problem should be solved as a design problem, not by changing the category.

Text direction requires caution. Moving labels to make a diagram aesthetically balanced can make a number appear in the wrong region. If the target script reads right to left, decide whether to mirror the circles, reverse label placement or leave the mathematics anchored. Geometry and membership are not inherently left-to-right; the critical requirement is that each set and region keeps its identity throughout the transformation.

Never make colour the sole carrier of category meaning. Labels, borders, patterns and explanatory text should tell the reader which group each region represents. Where a source relies on coloured overlays, check the legend and provide descriptive alternatives. Colour can help distinguish sets, but it does not replace a membership statement.

Write an accessible description that reconstructs the membership logic

The text equivalent of a Venn diagram should do more than say “two overlapping circles.” It should identify the universe, define each category, describe the overlap and exclusive regions, and include values if the chart gives them. For the example of two reading activities, a useful description could state the total number surveyed, how many selected only activity A, how many selected both, how many selected only B and how many selected neither. A screen-reader user can then reason from the same facts as a sighted reader.

For more complicated diagrams, a structured table or clearly headed list of membership combinations is often more useful than a long stream of undifferentiated prose. Make sure the text format distinguishes an empty region from an omitted value. The W3C Web Accessibility Initiative recommends that complex diagrams have meaningful text equivalents, with detail available beyond a short identification.

Check that the target-language description does not mix up notation when rendered as spoken text. A screen reader may pronounce ∩ or ∪ differently depending on settings. It is often helpful to give both the symbol and a plain-language explanation on first use. Someone who cannot inspect the image should still be able to answer the same membership question.

Translate the questions around the diagram, not only the diagram

In educational material, a Venn diagram is frequently paired with questions: “How many students chose at least one?”, “How many selected exactly two?”, or “How many are outside the union?” The translator must align the question with the visible regions. A common error is to make the prompt more fluent by replacing “at least one” with “one,” which changes the answer. Another is to drop “only” because the target sentence sounds smoother without it.

Use the diagram as a consistency test: if the translated question points to a different region from the source question, revise it. For three-set problems, draw a small answer key listing the membership patterns included by each expression. Then compare target-language wording against the key. This is especially helpful when an inclusive “or” lacks a direct natural equivalent.

Teaching these distinctions also strengthens ordinary language comprehension. Learners discover that words such as all, some, neither and except are not background decoration. They determine what a statement claims. Study the logic first, then practise natural wording that carries exactly the same boundary.

Review set logic in a separate verification pass

The first review checks language: spelling, readability, terminology and audience. The second checks truth conditions. For each category, ask who belongs; for each shaded region, test a hypothetical item; for each number, verify the underlying count; for each exclusion, confirm the universe. A translation that passes language review but fails these membership tests is not accurate.

Back-translate by asking a second reader to describe the membership rule without using the visual. If the source says “people who chose both” and the reader thinks “people who chose either,” the diagram has failed. If a number moves from the centre to an exclusive crescent, visual QA failed. If the total changes because the overlap was counted twice, arithmetic QA failed. Diagnose the specific failure rather than masking it with a new slogan.

A useful editorial record includes category definitions, set notation, region values, legend wording, open questions and the final reviewed layout. This modest extra work makes multilingual versions consistent when diagrams are reused in lessons, reports, interactive displays and accessibility descriptions.

Connect set language to wider vocabulary learning

Venn diagrams are a compact training ground for precise reading. They link mathematics to everyday words: inclusion, exclusion, overlap, exception, subset, alternative, union and intersection. Learners who can distinguish these concepts can reason more clearly about instructions, eligibility criteria, survey results and arguments. They also become more alert to translations that sound plausible but silently move boundaries.

Worked translation clinic: twenty-four membership decisions

All examples use hypothetical diagrams rather than real survey findings. Each one isolates a particular translation risk. Try expressing the correct membership rule as an ordinary sentence, then test it with one item that should qualify and one that should not.

1. Only A versus all of A

Suppose a label sits in the outer A crescent rather than over the whole circle. A translation mistake would be to call that region every member of A. The accurate version should instead say A and not B, preserving the exclusivity of the crescent. To catch the error, test a member of the central overlap against the target sentence. This check is more reliable than comparing the length or apparent similarity of two captions because it tests the reader’s membership decision.

Try a second pass without the picture: invent a hypothetical item and ask whether it belongs to the region described. If the target-language sentence admits an item that the original excludes, or excludes one that the source admits, it changes the set. Keep the corrected sentence short enough for the intended audience, but never remove a logical qualifier merely to save a few characters in a circle.

2. The entire union

Suppose both circles are shaded, including the centre. A translation mistake would be to write exactly one category. The accurate version should instead use A or B or both, according to the formal union. To catch the error, check that a member of both groups is included. This check is more reliable than comparing the length or apparent similarity of two captions because it tests the reader’s membership decision.

3. Exclusive choice

Suppose the two outer crescents are shaded while the overlap remains blank. A translation mistake would be to translate as inclusive or. The accurate version should instead say either category but not both. To catch the error, test a person in the overlap and confirm exclusion. This check is more reliable than comparing the length or apparent similarity of two captions because it tests the reader’s membership decision.

4. Neither category

Suppose the rectangle outside two circles is shaded. A translation mistake would be to write all people who dislike both topics. The accurate version should instead describe members of the defined universe who belong to neither set. To catch the error, do not infer attitudes from nonselection. This check is more reliable than comparing the length or apparent similarity of two captions because it tests the reader’s membership decision.

5. An unknown universe

Suppose the graphic lacks a title and a border definition. A translation mistake would be to assume the set concerns everyone worldwide. The accurate version should instead preserve a conditional or contextual description until the population is defined. To catch the error, ask for the originating questionnaire or caption. This check is more reliable than comparing the length or apparent similarity of two captions because it tests the reader’s membership decision.

6. A proper subset

Suppose circle A sits strictly inside B and B has a nonempty outer ring. A translation mistake would be to translate all B are A. The accurate version should instead state all A are B, with some B outside A. To catch the error, reverse-test the implication using an item in B-only. This check is more reliable than comparing the length or apparent similarity of two captions because it tests the reader’s membership decision.

7. A pairwise overlap

Suppose the A-B lens includes the region common to A, B and C. A translation mistake would be to exclude C automatically. The accurate version should instead say A and B, including those also in C, when that is the source rule. To catch the error, trace the shading boundaries instead of relying on ordinary phrasing. This check is more reliable than comparing the length or apparent similarity of two captions because it tests the reader’s membership decision.

8. Two groups only

Suppose a three-set figure shades A and B but not C. A translation mistake would be to write A and B with no qualifier. The accurate version should instead use A and B but not C. To catch the error, test a central ABC member and confirm exclusion. This check is more reliable than comparing the length or apparent similarity of two captions because it tests the reader’s membership decision.

9. An empty overlap

Suppose the intersection shows 0 respondents. A translation mistake would be to claim the two hobbies can never coexist. The accurate version should instead state that zero respondents in this sample selected both. To catch the error, distinguish an observed zero from logical impossibility. This check is more reliable than comparing the length or apparent similarity of two captions because it tests the reader’s membership decision.

10. A blank region

Suppose a shaded segment contains no printed number. A translation mistake would be to insert 0 automatically. The accurate version should instead leave the value unspecified until the source clarifies it. To catch the error, compare the data table and legend. This check is more reliable than comparing the length or apparent similarity of two captions because it tests the reader’s membership decision.

11. A region count

Suppose the A-only region shows 12, while overlap shows 8. A translation mistake would be to label the set A total as 12. The accurate version should instead say 12 are A-only and the A total is 20 in the stated example. To catch the error, sum the relevant regions. This check is more reliable than comparing the length or apparent similarity of two captions because it tests the reader’s membership decision.

12. A double-counting trap

Suppose A totals 20, B totals 13 and intersection totals 8. A translation mistake would be to add 20 and 13 as the union. The accurate version should instead subtract the shared 8 and report 25 for the union. To catch the error, verify the totals refer to the same population. This check is more reliable than comparing the length or apparent similarity of two captions because it tests the reader’s membership decision.

13. Responses and respondents

Suppose a multiple-response survey counts selected activities. A translation mistake would be to use number of people when the source counts mentions. The accurate version should instead retain the source unit and distinguish multiple selections. To catch the error, read the survey methodology. This check is more reliable than comparing the length or apparent similarity of two captions because it tests the reader’s membership decision.

14. More than five

Suppose set A contains values strictly greater than five. A translation mistake would be to include five after translating the threshold. The accurate version should instead keep strict inequality, excluding five. To catch the error, test the boundary value itself. This check is more reliable than comparing the length or apparent similarity of two captions because it tests the reader’s membership decision.

15. Five or more

Suppose set B includes the threshold of five. A translation mistake would be to change the label to more than five. The accurate version should instead use a non-strict minimum inclusive of five. To catch the error, test membership at five. This check is more reliable than comparing the length or apparent similarity of two captions because it tests the reader’s membership decision.

16. Some versus all

Suppose the source says some members of A are in B. A translation mistake would be to write every member of A is in B. The accurate version should instead retain the existential or partial claim. To catch the error, try to find a counterexample to the stronger statement. This check is more reliable than comparing the length or apparent similarity of two captions because it tests the reader’s membership decision.

17. Population versus sample

Suppose the circle labels use surveyed customers. A translation mistake would be to remove surveyed and claim all customers. The accurate version should instead keep the survey sample as the universe. To catch the error, check the source population note. This check is more reliable than comparing the length or apparent similarity of two captions because it tests the reader’s membership decision.

18. An unverified category

Suppose a poster uses the loose term ‘healthy food’ without a rule. A translation mistake would be to invent a regulatory definition. The accurate version should instead preserve the informal educational category or request a definition. To catch the error, avoid presenting a value judgement as an official classification. This check is more reliable than comparing the length or apparent similarity of two captions because it tests the reader’s membership decision.

19. A literary comparison

Suppose two story circles have character traits in the overlap. A translation mistake would be to treat the overlap as a counted statistical sample. The accurate version should instead translate it as a comparison of shared and differing traits. To catch the error, respect the pedagogical genre rather than applying unneeded arithmetic. This check is more reliable than comparing the length or apparent similarity of two captions because it tests the reader’s membership decision.

20. Right-to-left reflow

Suppose the labels are mirrored but the region values remain in their old physical positions. A translation mistake would be to assume the numbers still identify the intended region. The accurate version should instead anchor each number to its set-membership code before layout changes. To catch the error, compare the target to the source region register. This check is more reliable than comparing the length or apparent similarity of two captions because it tests the reader’s membership decision.

21. A third category omitted

Suppose a three-circle chart is cropped so set C’s label is missing. A translation mistake would be to guess its membership rule from colour. The accurate version should instead identify the unresolved category and request an uncropped source. To catch the error, do not assign central values to an unnamed group. This check is more reliable than comparing the length or apparent similarity of two captions because it tests the reader’s membership decision.

22. A legend using colour

Suppose shades identify three categories but colour disappears in printing. A translation mistake would be to leave only grey circles. The accurate version should instead add text labels or patterns that identify each set. To catch the error, test comprehension without relying on colour. This check is more reliable than comparing the length or apparent similarity of two captions because it tests the reader’s membership decision.

23. A question says at least one

Suppose an exercise asks how many participated in one or more activities. A translation mistake would be to translate as exactly one activity. The accurate version should instead retain inclusive at least one and count the union. To catch the error, include the overlap in the answer key. This check is more reliable than comparing the length or apparent similarity of two captions because it tests the reader’s membership decision.

24. A complex alt description

Suppose a three-set chart shows eight numbered membership regions. A translation mistake would be to use ‘three circles overlap’ as the complete description. The accurate version should instead provide category definitions and an ordered region ledger with all eight membership combinations. To catch the error, ask a nonvisual reader to calculate a set total from the description. This check is more reliable than comparing the length or apparent similarity of two captions because it tests the reader’s membership decision.

A final bilingual set-mapping exercise

Imagine twenty-five fictional survey participants. Eleven selected activity A, fourteen selected activity B, and five selected both. First calculate the A-only and B-only regions and the union. Then decide how many selected neither if the universe really consists of twenty-five people. Record those numbers in a region ledger before translating anything: A-only 6, both 5, B-only 9, neither 5. Now write the exercise question in a second language. Does “at least one” still include the overlap? Does “neither” still refer to the surveyed universe rather than everybody outside it?

Next introduce a third activity and assign an explicit value to every membership pattern. Ask one bilingual reader to translate the labels, another to check the region codes, and a third to answer the problem using only the translated diagram. When the answer changes, identify whether the cause is vocabulary, number placement, incomplete scope or a mathematical misconception. This is a diagnostic process, not an exercise in sounding elegant.

The easiest reliable way to translate Venn diagrams is to treat every circle as a definition and every region as a truth condition. Names, numbers, overlaps and exclusions must remain attached to their original membership rules. Once the logic is secure, the target language can be natural, concise and readable without quietly changing the answer.
