Most final consonants in French are silent: the s in les chats, the t in petit, the d in grand. A final e is usually silent too. Liaison is when one of those silent consonants is pronounced because the next word starts with a vowel sound, so les amis sounds like “lay-zah-mee.” Some liaisons are required, some forbidden.
As a rule of thumb, final s, x, z, t, d and p are silent: Paris, le prix, le nez, le chat, grand, trop. The letters c, r, f and l at the end of a word are usually pronounced, which American teachers often summarize as “careful”: avec, finir, neuf, le sel. Both halves of the rule have exceptions worth knowing early.
| Word | Final letter sounded? | Why it matters |
|---|---|---|
| Paris, trop, grand | no | The default for s, p, d and t. |
| finir, avec, neuf, sel | yes | The “careful” letters. |
| parler, manger, le boulanger | no | Infinitives in -er and many nouns in -er end in an “ay” sound, with no r. |
| blanc, gentil | no | Common exceptions to the “careful” rule. |
| le bus, le fils, le sud | yes | Exceptions to the silent-consonant rule. Fils (son) sounds like “feess,” with no l. |
| il est (he is) / l’est (the east) | no / yes | Same spelling, different words: est meaning “is” sounds like “eh.” |
English marks the plural on the noun: cat, cats. In French, le chat and les chats have the same noun sound. The plural is heard on the article, le versus les, or on the verb. Pronouncing the s in les chats is one of the clearest giveaways of an English accent.
The same goes for verbs. The -ent ending of the ils and elles form is completely silent: il parle and ils parlent sound identical. English speakers tend to pronounce it like the end of “parent,” which turns the verb into a different word. Compare ils président (they preside), which sounds like “eel pray-zeed,” with le président, where the -ent is a nasal vowel. Context, not spelling, tells you which one you have.
A final e is silent, but it switches on the consonant before it. That is how you hear gender: petit has no t sound, petite does; grand ends in a nasal vowel, grande ends in a d; français ends in “ay,” française ends in a z sound. If you drop these consonants on feminine forms, French speakers will hear the masculine.
Plus is the famous double trap. Je n’en veux plus, with a silent s, means “I don’t want any more.” J’en veux plus, with the s pronounced, means “I want more.” Since casual speech often drops the ne, that one s carries the whole meaning.
When a silent final consonant comes back in liaison, it attaches to the next word’s first syllable, and some letters change sound on the way.
| Written letter | Sounds like | Example |
|---|---|---|
| s, x, z | z | les amis, deux enfants, chez elle |
| t | t | petit ami, c’est un livre |
| d | t | un grand homme, prend-il |
| n | n | un ami, mon oncle, bon appétit |
| f | v | only in neuf ans and neuf heures |
| Context | Example (no liaison at the bar) |
|---|---|
| After et | un café et | un croissant |
| Before an h aspiré | les | haricots, les | héros, en | haut |
| After a singular noun | un étudiant | américain |
| Before onze and oui | les | onze joueurs, un | oui |
The t in et is never pronounced, in liaison or anywhere else. English speakers who have just learned liaison often overapply it here, and it sounds immediately wrong.
Between these two lists sit the optional liaisons: after est, sont, suis and other verb forms, after pas, and after plural nouns. The more of them you make, the more formal you sound. In conversation, c’est un is nearly always linked, while je suis allé is often said without the z. If you are unsure, skipping an optional liaison is the safer error.
The French h is never pronounced. What differs is how the word behaves. An h muet acts like a vowel: l’homme, les hommes with a z, l’hôtel, l’heure, l’hiver, l’histoire. An h aspiré blocks both elision and liaison: le haricot, les haricots with no z, le héros, la honte, le hibou, le homard, le hasard, le hockey. Dictionaries mark h aspiré words, often with an asterisk. The classic pair is le héros but l’héroïne: same root, opposite behavior.
| Number | Alone | Before a consonant | Before a vowel |
|---|---|---|---|
| six, dix | final s heard | silent: six livres | z sound: six amis |
| huit | t heard | silent: huit jours | t heard: huit ans |
| neuf | f heard | f heard: neuf livres | v only in neuf ans, neuf heures |
| vingt | t silent | t silent: vingt livres | t heard: vingt ans |
Liaison is learned by ear, in chunks, not by rule lists. Say les amis, vous êtes, un grand hôtel and six heures out loud until they come out as single words, then use them in real sentences with someone who will notice when a z goes missing.
In liaison, a consonant that is normally silent is pronounced before a vowel, as in les amis. In enchaînement, a consonant that is always pronounced simply slides onto the next word, as in il arrive or avec elle.
Check a French dictionary, which marks h aspiré words, often with an asterisk. In practice, learn the common ones as a set with their article: le haricot, le héros, la honte, le hibou, le homard, le hasard.
They skip many optional ones, especially after verbs and after pas. They never skip the required ones, such as les amis, nous avons or un homme, so those are the ones to master first.
Many final consonants were pronounced in older French. The sounds faded but the spelling stayed, and liaison is the place where some of those old consonants still surface.
