Why Liaison Matters
Liaison is the pronunciation of an otherwise silent final consonant before a vowel sound. Its use is not arbitrary; it is governed by clear rules that distinguish obligatory, facultative, and forbidden liaisons.
The Three Categories of Liaison
| Category | Context | Example |
|---|---|---|
| obligatoire | After determiner + noun (les‿amis), pronoun + verb (nous‿avons), preposition + noun (dans‿une heure) | les‿amis, nous‿avons, dans‿une heure |
| facultative | After a plural noun + adjective (des enfants‿adorables), between auxiliary and past participle (elle est‿allée) | des enfants‿adorables, elle est‿allée |
| interdite | After a singular noun (un chat‿endormi), before h aspiré (les‿héros – incorrect, actually h aspiré forbids liaison, so 'les héros'), after et (lui et‿elle), after a question word (Quand‿est‑il… – actually quand triggers liaison, wait, 'Quand‿est-il' is obligatory. I'll correct: forbidden after 'et', after singular noun, before h aspiré) | un chat endormi, les héros, lui et elle |
Key Points
Obligatory liaison occurs in tightly knit grammatical groups. Facultative liaison is a matter of register: the more formal the speech, the more liaisons are made. Forbidden liaison would sound unnatural or lead to confusion. Special attention must be paid to h aspiré words such as le héros (no liaison) versus l’heure (liaison because h muet).
Examples
- Nous‿avons‿un‿ami qui habite en France.Obligatory liaisons: nous‿avons, un‿ami.
- Les enfants‿adorables sont rentrés.Facultative liaison after plural noun: enfants‿adorables.
