What is a forbidden liaison in french?

A liaison is the pronunciation in one syllable of the final consonant of a word, normally unpronounced, with the initial vowel of the following word. There are many situations where the connection is never made. Therefore, we say that it is prohibited. Linking is not allowed when:

• There is a pause between 2 words,
• There is a punctuation mark between 2 words,
• The function of the word prohibits it.

The 11 most frequent cases are presented in the following:

1. after a singular noun
2. between a nominal group and a verb
3. between a subject nominal group and another group
4. after the pronoun of an inverse verb
5. after the pronouns un and aucun

7. after quelqu’un
8. after interrogative adverbs
9. before an aspirated h
