Learn French: Je veux sortir ce soir. - I want to go out tonight.

The verb vouloir (to want) is irregular. For the I form (je), it ends with an x, making it je veux. The casual you form also uses an x (tu veux), while the he/she/it form uses a t (il veut).

Why is the verb sortir not conjugated?

When two verbs are used together in a phrase, only the first one is conjugated (matched to the person doing the action). Because veux is already conjugated for je, the second verb, sortir (to go out), stays in its basic, unchanged dictionary form (the infinitive).

Why do we use ce before soir?

The word ce means this. We use ce here because soir (evening) is a masculine word. If the word were feminine, like nuit (night), you would have to use cette instead to say cette nuit.

The translation says tonight, but doesn't soir mean evening?

Yes! The word soir means evening, so ce soir literally means this evening. However, French speakers use ce soir as the standard and most natural way to say tonight when talking about plans for later in the day.
