What words in French have a silent s?

You are correct! In French, the letter "s" is often silent at the end of a word.

Here are some examples:

Singular nouns:

* Le chat (the cat)

* La chaise (the chair)

* Le prix (the price)

* Le bus (the bus)

* La souris (the mouse)

Plural nouns:

* Les chats (the cats)

* Les chaises (the chairs)

* Les prix (the prices)

* Les bus (the buses)

* Les souris (the mice)

Other words:

* Tous (all)

* Puis (then)

* Sans (without)

* Après (after)

* Plus (more)

Important note:

While the "s" is usually silent at the end of a word, there are some exceptions. For example, the "s" is pronounced in words like:

* Les oiseaux (the birds) - the "s" is pronounced in this case due to the presence of the "x" sound

* Le mois (the month) - the "s" is pronounced because it's followed by a vowel.

I hope this helps!
