In French grammar, the future tense is used to talk about actions or events that will happen in the future. The future tense is formed by using the infinitive form of the verb and adding the appropriate ending. The endings for the future tense are –ai, -as, -a, -ons, -ez, and –ont for regular verbs, and the irregular verbs have their own conjugations.
Examples:
Je parlerai. (I will speak.)
Nous mangerons. (We will eat.)
Il viendra. (He will come.)
It’s worth noting that there are two other ways to express the future in French, the “near future” (le futur proche) and the “conditional” (le conditionnel) which are used to express more immediacy or more uncertainty respectively.
