Pronunciation

Liaison: when liaison takes place

In careful colloquial speech, liaison takes place:

• between the article and the noun or the following adjective: un ami, les amis
  
  
• between a pronominal adjective and the following noun or adjective: certains enfants
  
  
• between adjective and noun: grand homme, grand effort
  
  
• between the personal pronouns and the following verbs : nous avons, ils ont
  
  
• between verbs and personal pronouns in interrogative form: ont-ils?
  
  
• usually between auxiliary verbs and participe passé in the forms of compound tenses: nous avons aimé (but not as, auras, eusses)
  
  
• between the prepositions and the following word: chez un ami, dans aucun cas (but not after the preposition vers)
  
  
• between an adverb and a word it defines, especially when the adverb is très, bien, tout
  
  
• in many ossified expressions.

There are even more liaisons in the solemn pronunciation.

However, one cannot use liaison:

• after et: et un
  
  
• after vers: vers elle
  
  
• before h aspirated : les haches
  
  
• before un, huit, onze.
