Liaison (pronounced lee-ay-zohn) is a unique feature of French pronunciation where a normally silent consonant at the end of a word is pronounced when the following word begins with a vowel. This creates a smooth connection between words and enhances the natural flow of speech.

1. When Liaison Occurs

• Obligatory Liaison: In certain grammatical contexts, liaison is mandatory.
  • Article/Adjective + Noun: les amis (lay-za-mee, friends), un grand arbre (uh~grahn-tarbr, a big tree)
  • Pronoun + Verb: nous allons (noo-za-lohn, we go), ils ont (eel-zohn, they have)
  • Certain Adverbs + Adjective/Adverb: très intéressant (tray-za~tay-ray-sahn, very interesting), bien sûr (bee-ehn-soor, of course)
  • Number + Noun: deux hommes (duh-zom, two men), six enfants (see-zohn-fahn, six children)
• Optional Liaison: While not grammatically required, liaison is often used for smoother pronunciation.
  • Noun + Adjective: un petit enfant (uh~p(e)tee-tahn-fahn, a small child) - Without liaison, it would sound like "uh~p(e)tee-ahn-fahn," which is unnatural.
  • Verb + Pronoun: vous avez (voo-za-vay, you have) - Without liaison, it would sound like "voo-a-vay," which is unnatural.
• Forbidden Liaison: Liaison never occurs in certain situations.
  • Before a pause (comma, period, etc.): Il est grand et fort. (ee-lay-grahn-ay-for, He is tall and strong.) - No liaison before "et."
  • Before an "h aspiré": les héros (lay-ay-roh, heroes) - No liaison before an "h aspiré" (aspirate h).

2. Pronunciation Changes in Liaison

The consonant pronounced in liaison can change depending on the following vowel.

• [n] → [n]: un an (uh-nahn, one year)
• [s] → [z]: les amis (lay-za-mee, friends)
• [x] → [z]: deux amis (duh-za-mee, two friends)
• [d] → [t]: quand il (kahn-teel, when he)
• [p] → [p]: trop aimable (troh-peh-mable, very kind)
• [f] → [v]: neuf ans (nuh-vahn, nine years)

3. Tips for Learning Liaison

• Learn the liaison rules and memorize the exceptions.
• Listen to and imitate native French speakers to get used to liaison.
• Liaison is not only a grammatical rule but also a way to achieve natural pronunciation, so practice consistently to develop a feel for it.

4. Important Notes

• Liaison is an important feature of French, but it doesn't apply in all situations.
• Excessive liaison can lead to unnatural pronunciation, so be mindful.

Example Dialogue Explaining Liaison

Teacher: Today, we'll learn about liaison in French. What do you think liaison is?

Student: Um... it's when words connect smoothly?

Teacher: Exactly! More specifically, it's the phenomenon where a silent consonant at the end of a word is pronounced before a vowel in the next word. For example, "les amis" is pronounced "lay-za-mee."

Student: Oh, I see! So, do we always have to use liaison?

Teacher: No, not always. There are grammatical rules, and sometimes it's used optionally for smoother pronunciation.

Student: Could you explain in more detail when to use liaison?

Teacher: For example, when an article or adjective comes before a noun, or a pronoun comes before a verb, liaison is mandatory. But it's not used before pauses or "h aspiré" sounds.

Student: I see. It's a bit complicated, but I'll try to get used to it!

Teacher: Yes, with practice, you'll get the hang of it. Liaison is an important element that makes French pronunciation beautiful, so be sure to master it!
