How to Say "Nine Thirty" in French

neuf heures et demie

The English phrase "nine thirty" can be translated into French as neuf heures et demie.

This phrase is used to state that the time is half past nine.

How does it change in a sentence?

In the phrase neuf heures et demie, the word demie is feminine to agree with the feminine noun heure.

Avoid using the masculine form demi. English speakers often mistakenly say neuf heures et demi instead of the correct feminine neuf heures et demie.

The word neuf is a homonym in French. Depending on the context, it can mean the number 'nine' or the adjective 'new'.
If you want to express 'nine and a half' in terms of quantities other than time, such as 'nine and a half liters', you must use the masculine demi instead of the feminine demie.
The word neuf used for the number 'nine' shares a common ancestor with the English word 'nine', both coming from the Proto-Indo-European root *h₁néwn̥.
