- A French-2 student knows that the number vingt (twenty) behaves differently in liaison depending on its context. In vingt ans (twenty years), the /t/ is pronounced via liaison. In vingt garçons (twenty boys), the /t/ is silent. The student then encounters vingt et un (twenty-one) and must decide whether liaison occurs between vingt and et. Which analysis is correct?
Answer: No liaison occurs between vingt and et because the conjunction et blocks liaison on its left side as well as its right side — nothing links into et from a preceding word, so the /t/ of vingt remains silent, and vingt et un is pronounced [vɛ̃ e œ̃].
Whenever you see a liaison question in French, you need to think beyond "does the next word start with a vowel?" and ask "does the grammatical environment permit liaison here?" One of the most important blocking rules involves the conjunction et (and).
In French, et is a double-sided liaison blocker: nothing links into it from the left, and nothing links out of it to the right. This is why vingt et un is pronounced [vɛ̃ e œ̃] — the /t/ of vingt stays silent before et even though et begins with a vowel. The liaison you hear in vingt ans happens because ans is a noun directly following the number, with no conjunction blocking the connection. That makes D the correct analysis.
Choice A makes a plausible-sounding phonological argument — et does begin with /e/, just like ans begins with /ɑ̃/ — but it ignores the grammatical structure. Liaison is not purely phonological; syntactic category matters, and et is categorically exempt. Choice B compounds this error by claiming numbers always trigger liaison before any vowel-initial word, which overstates the rule and again ignores *et*'s special status. Choice C goes too far in the opposite direction, claiming numbers above ten are globally exempt from liaison — this is false, since vingt ans is a standard example of obligatory liaison with numbers.
Your study tip: memorize et as a liaison firewall — it blocks on both sides. A quick memory hook is "et stands alone." Any time you see et in a liaison question, no linking crosses it.
- A student reads aloud un petit homme and correctly produces liaison, linking the /t/ of petit to homme. The student then reads un petit hibou (a little owl) and produces the same liaison, linking the /t/ of petit to hibou. A native speaker corrects only the second production. Which explanation best accounts for why one liaison is correct and the other is not?
Answer: Homme has a mute h (h muet), so it is treated as vowel-initial and liaison with petit is obligatory; hibou has an aspirate h (h aspiré), so it acts as consonant-initial and liaison with petit is forbidden, making the student's second production an error.
Whenever you encounter a question about French liaison, the key concept to master is the distinction between h muet (mute h) and h aspiré (aspirate h) — two categories of words that look similar on paper but behave very differently phonologically.
In French, the letter h is never actually pronounced, but its grammatical classification determines whether liaison and elision can occur. Words with h muet are treated as if they begin with a vowel: the preceding consonant links directly to them, and elision occurs (l'homme, not le homme). Words with h aspiré create an invisible "wall" — they block liaison and elision (le hibou, never l'hibou), behaving as though they begin with a consonant, even though no consonant sound is actually there. This is why un petit homme requires liaison (the /t/ links to homme), while un petit hibou forbids it. Answer B correctly captures this distinction: homme is h muet, making the liaison with petit obligatory, while hibou is h aspiré, making the student's liaison an error — exactly what the native speaker corrected.
Answer A is wrong because it falsely claims h always triggers liaison; the letter h alone tells you nothing — the muet/aspiré classification does. Answer C is wrong because hibou does NOT have h muet; misclassifying it as such is a common trap. Answer D is wrong because it invents a frequency-based explanation that has no basis in French grammar — the h muet/aspiré distinction is purely lexical and must be memorized word by word.
Your best study strategy: keep a running list of common h aspiré words (hibou, haricot, honte, honte, hauteur) since they must be learned individually — there is no pronunciation clue to guide you.
- The student produces liaison in Phrase 1 but not in Phrase 2. A classmate claims the student made an error in Phrase 2 by failing to link the /z/ of vous to savez. Which explanation best evaluates both productions?
Answer: Liaison in vous habitez is obligatory because vous is a subject pronoun preceding a vowel-initial verb; liaison in vous savez is phonologically impossible because savez begins with /s/, a consonant — the student is correct in both phrases, and the classmate's criticism is unfounded.
Whenever you see a question about French liaison, train yourself to ask two things: Is liaison required here? and Is liaison even phonologically possible? Liaison only occurs when a normally silent final consonant links to a vowel-initial word that follows — if the next word begins with a consonant, there is simply no vowel to link to, making liaison impossible by definition.
In vous habitez, vous ends in a latent /z/ and habitez begins with a vowel /a/. Because vous is a subject pronoun directly preceding its verb, this is a classic obligatory liaison context — skipping it would be the actual error. In vous savez, savez begins with the consonant /s/. There is no vowel onset to receive the /z/, so liaison cannot occur at all — it isn't optional or forbidden by a stylistic rule, it is simply phonologically impossible. The student's two productions are both correct, and the classmate's criticism is unfounded. This confirms D as the right answer.
Choice A is wrong because it treats both liaisons as obligatory, ignoring the consonant onset of savez entirely — a fundamental misunderstanding of how liaison works. Choice B incorrectly frames the vous savez case as "forbidden" liaison rather than phonologically impossible, and confusingly implies the student avoided an error "for the wrong reason." Choice C mischaracterizes vous savez as an optional liaison context, suggesting style governs the choice when in fact consonant onset makes the question moot.
Study tip: Always check what sound the second word begins with before applying any liaison rule — consonant onset eliminates liaison as a possibility before rules about obligation or style even apply.
- In French, the word et (meaning 'and') is commonly described as a liaison blocker. Which of the following sentences correctly applies this rule, and why?
Answer: Un garçon et une fille — no liaison occurs between et and une because et is a liaison blocker: the /t/ of et is never carried over to the following word, even though une begins with a vowel.
When studying French pronunciation rules, it helps to understand that liaison — the linking of a word's final consonant to the next word's initial vowel — is not automatic everywhere. Certain words act as liaison blockers, meaning the linking simply never happens after them, regardless of what follows.
The word et (and) is the classic example. Even though et ends in a t and the following word may begin with a vowel, the /t/ sound is never carried over. This is true in both spoken and written French — it's not a formality issue, it's a firm phonological rule. So in un garçon et une fille, there is no liaison between et and une, even though une begins with a vowel. That makes C the correct answer.
A is wrong because it claims liaison is "obligatory whenever two words meet across a vowel boundary." This overgeneralizes the rule — liaison depends heavily on which specific words are involved, and liaison blockers like et are precisely the exceptions that disprove this logic.
B is wrong on two counts: it misidentifies the example sentence as containing liaison, and it falsely claims that et only blocks liaison in written French. The rule applies universally in spoken French as well.
D is wrong because "high-frequency grammatical words always trigger liaison" is simply not a rule in French. Et is indeed high-frequency, but frequency alone never overrides liaison-blocking behavior.
Your study tip: memorize et as the go-to example of a liaison blocker — exam questions frequently test whether you know that a vowel after et does not trigger linking.
- Which sentence contains a forbidden liaison, and what is the grammatical reason for it?
Answer: Sentence A contains the forbidden liaison: étudiants arrivent is forbidden because liaison between a plural noun subject and its following verb is categorically prohibited in standard French, even though étudiants ends in a silent s and arrivent begins with a vowel.
Whenever you see a liaison question in French, your first move should be to identify the grammatical category of the word before the vowel — because liaison rules depend entirely on what type of word is involved, not just whether the sounds "could" connect.
In French, there are three tiers of liaison: obligatory, optional, and forbidden. The noun-subject/verb boundary is one of the clearest examples of a forbidden liaison. Even though étudiants ends in a silent s and arrivent begins with a vowel — conditions that might tempt you to link them — standard French categorically prohibits liaison across this boundary. Producing étudiants‿arrivent would sound hypercorrect or simply wrong to a native speaker. That makes Answer A correct: the forbidden liaison occurs in Sentence A.
Answer B is wrong because it reverses the logic. Ils arrivent actually contains an obligatory liaison — subject pronouns like il, ils, on, nous, and vous must link to a following verb that begins with a vowel. Saying ils arrivent without the liaison would be the error, not with it.
Answer C is wrong because it misidentifies ils arrivent as forbidden. Pronouns and nouns behave differently in liaison; a pronoun subject does not "inherit" noun-subject status for liaison purposes — the rules are category-based, not referent-based.
Answer D is wrong because neither liaison here is optional. One is forbidden, the other obligatory — there is no speaker discretion involved.
Study tip: Memorize liaison by grammatical boundary, not by sound alone. The noun-subject/verb boundary is always forbidden; the personal-pronoun/verb boundary is always obligatory — these two are commonly tested together precisely because students confuse them.
- When a French speaker produces the liaison in ils ont (they have), the final consonant of ils that is pronounced is /z/. When liaison occurs in nous allons (we are going), the linked consonant is also /z/. A student claims these two liaisons are phonologically identical in their output. Which response most accurately evaluates this claim?
Answer: The claim is correct: in ils ont, the silent s of ils surfaces as /z/ through obligatory pronoun-before-verb liaison; in nous allons, the silent s of nous also surfaces as /z/ through the same obligatory pronoun-before-verb liaison — both liaisons produce the identical phonological segment /z/.
Liaison in French is a phonological process where a normally silent final consonant is pronounced before a word beginning with a vowel or silent h. When evaluating whether two liaisons are "identical," you need to examine both the phonological output (the actual sound produced) and the grammatical context (what triggers it).
In ils ont, ils carries a latent /z/ from its written s, and liaison is obligatory between a subject pronoun and its following verb — producing /z/. In nous allons, nous similarly carries a latent /z/ from its written s, and the same obligatory pronoun-before-verb rule applies — also producing /z/. The sound, the source, and the grammatical trigger are all parallel. Answer A correctly identifies this symmetry, making the student's claim valid.
Answer B is wrong because it misclassifies ils ont as a "forbidden liaison between a plural noun subject and its verb." Ils is a pronoun, not a noun — pronoun-verb liaison is obligatory, not forbidden. This is a critical grammatical distinction the question is designed to test.
Answer C is wrong because it incorrectly labels ils ont liaison as "optional." Both liaisons here are obligatory in standard French. There is no register-based optionality between these two examples.
Answer D is the most tempting distractor, but it's phonologically incorrect. The s in nous does not surface as voiceless /s/ before a vowel — liaison consonants in French are always voiced /z/ when derived from a written s in this context. The claim about devoicing is fabricated.
Study tip: Always verify whether a subject is a pronoun or noun before applying liaison rules — pronoun-verb liaison is obligatory, but noun-verb liaison is forbidden.
- In Speaker A's line Comment allez-vous?, a student produces a liaison between Comment and allez, pronouncing a /t/ sound. A more advanced student says this is an error. Which of the following best explains whether this liaison is correct, optional, or forbidden?
Answer: The liaison is forbidden because comment is an interrogative adverb, and liaison after interrogative adverbs such as comment, quand, and combien is categorically prohibited in standard French — the /t/ of comment is never pronounced before allez regardless of register.
When tackling French liaison questions, you need to distinguish between three categories: obligatory liaison, optional liaison, and forbidden liaison. Interrogative adverbs are one of the clearest cases of the forbidden category.
In standard French, liaison after interrogative adverbs like comment, quand, combien, and où is prohibited. Even though comment ends in a written t and allez begins with a vowel — conditions that often trigger liaison — the /t/ is never pronounced here. This is a hard rule, not a stylistic preference. So B is correct: producing a /t/ sound between comment and allez is a genuine error, not a stylistic choice.
Choice A is wrong because it invents a false rule. Not every question word ending in a written consonant triggers liaison — the category of word matters enormously, and interrogative adverbs are specifically excluded. Choice C is tempting because "optional liaison" feels like a safe, nuanced middle ground, but it misrepresents the facts. Liaison after comment isn't a register-dependent stylistic option; it's simply forbidden at all registers. Choice D incorrectly applies the logic of fixed expressions. While some frozen phrases do require liaison (e.g., tout à coup), Comment allez-vous? does not override the categorical rule against liaison after interrogative adverbs — being a common greeting doesn't automatically make every internal boundary a liaison site.
A helpful memory trick: think of the "forbidden quartet" — comment, quand, combien, où — and remember that no matter what follows them, the final consonant stays silent. On liaison questions, always identify the grammatical category of the word before deciding whether liaison applies.
- A student hears a native French speaker say un grand ami and correctly links the /d/ of grand to the vowel of ami, producing a /t/ sound. The student then applies the same logic to un grand garçon and links grand to garçon, again producing a /t/ sound. Which statement best explains the difference in correctness between these two cases?
Answer: The first liaison is correct because adjective-before-noun liaison is obligatory when the noun begins with a vowel or mute h, while the second is an error because liaison does not occur before a consonant-initial word — there is no vowel onset to link to, so inserting a /t/ before garçon is phonologically impossible.
Whenever you encounter a question about French liaison, the key framework to apply is: what triggers liaison, and what blocks it? Liaison in French requires two conditions: a word with a latent (silent) final consonant, followed by a word beginning with a vowel or mute h. The consonant then "links" to the next syllable.
In un grand ami, grand precedes a vowel-initial noun, so liaison is obligatory — the latent /d/ surfaces as /t/ (a standard devoicing), producing /grɑ̃.t‿a.mi/. This is a textbook example of obligatory adjective-noun liaison. In un grand garçon, however, garçon begins with /g/, a consonant. There is no vowel onset to link to, so liaison simply cannot occur — there is no phonological "bridge" available. Inserting a /t/ before garçon would be an error with no basis in French phonology. Answer C captures this precisely.
Answer A is wrong because liaison is not triggered before consonant-initial words — the claim that it occurs "regardless of the initial sound" contradicts how liaison fundamentally works. Answer B contains a reasonable first clause but goes too far by calling liaison "categorically prohibited" before consonant-initial nouns as a rule unto itself, rather than explaining that it's simply phonologically impossible without a vowel to link to — the framing misleads you about the mechanism. Answer D inverts reality entirely: liaison before a vowel is obligatory (not optional), and grand garçon has no special compound status that forces liaison before a consonant.
Your study tip: always check the initial sound of the second word first — if it's a consonant, liaison is off the table before any other rule even applies.
