Three words with the same glide

Read each word as one syllable
WordIPAMeaningShort phrase
huit/ɥit/eightà huit heures
nuit/nɥi/nightbonne nuit
lui/lɥi/him; to him or heravec lui

The symbol /ɥ/ names the brief rounded movement before the vowel. In nuit, the /n/ comes first; in lui, the /l/ comes first. The /i/ carries the syllable. Keep the movement quick: stretching the first part into a full vowel can turn one syllable into two.

How do you pronounce huit, nuit and lui?

Try the movement slowly, then join it

  • Say French u /y/: the tongue is forward and the lips are rounded.
  • Keep the tongue towards the front as you move into i /i/. Let the lips relax.
  • Shorten the first movement until the two parts fit one beat: lui.
  • Add a phrase: avec lui, then Je travaille avec lui. Compare it with a spoken model.

tu /ty/you

Focus: a full rounded vowel /y/

une voyelle : /y/

Tu viens ?
Are you coming?

lui /lɥi/him

Focus: a quick front rounded glide followed by /i/

une syllabe : /lɥi/

Je travaille avec lui.
I work with him.

oui /wi/yes

Focus: the back rounded glide /w/

une syllabe : /wi/

Oui, je viens.
Yes, I’m coming.

Keep the word inside a phrase

Il arrive à huit heures.

He arrives at eight o’clock.

Say the /t/ in huit heures. It belongs to the end of huit, separate from the initial glide.

La nuit est calme.

The night is quiet.

The word nuit is /nɥi/ here: the written final t is silent.

Vous pouvez lui laisser un message.

You can leave him or her a message.

Here lui means “to him or her”. Keep it short between the surrounding words.
