Future tense

The future tense is formed by adding an ending to the infinitive form of the verb (the unconjugated form.)  All verbs -AR, -ER, -IR use the same endings:

PASAR + ending

Yo pasaré Nosotros pasaremos
pasarás Vosotros pasaréis
Él, Ella, Usted pasará Ellos,Ellas,Ustedes pasarán

Yo pasaré tiempo con mis amigos. = I will pass/spend time with my friends.

Be careful with accent marks! They are very important when communicating the future.
