French optional liaisons

Some French liaisons in front of a vowel or h muet are optional, so it’s up to you to decide whether to pronounce them. However, that decision matters: more liaisons means more formal speech, so fewer liaisons obviously means more informal, possibly even familiar speech.

Here are types of liaisons from most common to least common: even teenagers will usually pronounce the first type of liaison, but very few people will pronounce the last type. The ones in the middle are where it starts getting tricky. 😉

Each sound file includes the phrase pronounced with the liaison and then without.

1. After plural nouns

des livres utiles[day leev reu zu teel][day lee vru teel]*
les hommes arrivent[lay zuhm zah reev][lay zuh mah reev]*

2. Between two-part verbal structures**

ils ont eu[eel zo(n) tu][eel zo(n) u]
je suis allé[zheu swee zah lay][zheu swee ah lay]
tu vas aller[tu vah zah lay][tu vah ah lay]

3. Present tense of être + adjectiveadverb, or noun

il est heureux[ee lay teu reu][ee lay eu reu]
il est ici[ee lay tee see][ee lay ee see]
il est idiot[ee lay tee dyoh][ee lay i dyoh]

4. After multi-syllable adverbs and prepositions

après être venu[ah preh zehtr][ah preh ehtr]
assez utile[ah say zu teel][ah say u teel]
depuis un an[deu pwee zu(n)][de pwee u(n)]
tellement avare[tehl ma(n) tah var][tehl ma(n) ah var]

5. After some conjunctions***

mais enfin[meh za(n) feh(n)][meh a(n) feh(n)]
puis on est arrivé[pwee zo(n)][pwee o(n)]

6. Verb + article, noun, or preposition

This liaison is found only in very formal French.

Elle prend un livre[pra(n) tu(n)][pra(n) u(n)]
Ils arriveront à midi[ah ree vro(n) tah][ah ree vro(n) ah]

 Notes

* If you don’t make a liaison with the normally silent s at the end of livres and hommes, the always pronounced vr and m still require enchaînement.

** Two-part verb structures:
