Future tense (Irregular verbs) 1

The five most important irregular future stems — Priority five: tener → tendr- (I'll have), poner → pondr- (I'll put), venir → vendr- (I'll come), decir → dir- (I'll say), hacer → har- (I'll do/make). These five cover the most frequent irregular futures in everyday speech.

Adding the same endings as regular futures — Once you have the irregular stem, the endings are always the same: -é, -ás, -á, -emos, -éis, -án. So: tendré, tendrás, tendrá, tendremos, tendréis, tendrán. The hardest part is learning the stems — the endings themselves never change.

Also used for probability about the present — Irregular future forms appear frequently in questions and statements expressing present probability: ¿Dónde estará? (Where can he be?) Tendrá hambre (He must be hungry). No sé lo que querrán (I don't know what they can want). This use is just as common as referring to actual future events.
