Yes in French is rarely just oui. The choice between oui, si, and their informal variants carries information about whether you are agreeing, contradicting a negative, or expressing enthusiasm or reluctance.

Pronunciation of oui

French	IPA	Pronunciation guide
oui	/wi/	Like the English word wee

Oui is a single syllable. The ou combination in oui is not pronounced like the ou in soup; it is a glide sound. The whole word sounds like wee in English. Many learners mispronounce it as oh-wee (two syllables) or oo-ee, both of which are incorrect.

FAQ

Why is si used for yes in French when contradicting a negative, but not in Spanish?

Spanish uses sí universally. French is unusual among Romance languages in having a dedicated word si for contradicting negatives. It comes from Latin sic (thus / so it is). German and Swedish have similar systems (doch in German, jo in Swedish).

Is ouais considered rude?

Ouais is not rude; it is simply informal. Using it with close friends, peers, or in casual situations is entirely normal. Using it with a boss, a professor, or in a formal interview would be seen as too casual, similar to saying yeah in an English job interview when yes is expected.

What does mouais signal and when do French speakers use it?

Mouais signals reluctant, unenthusiastic agreement. The speaker is technically saying yes but conveying reservations or lack of enthusiasm. It is similar to meh or I suppose in English. French speakers use it when they want to agree without pretending enthusiasm they do not feel.
