the future tense is typically used for verbs whose action will take place sometime in the future. Generally, it is the equivalent of the “will + verb” form in English in sentences such as “I will go” or “she will eat.”
With regular verbs, the future tense is formed by adding endings to the infinitive. All infinitives use exactly the same endings as shown in boldface in the list below

tú                               -ás
él, ella, Ud.                
nosotros,nosotras       -emos

vosotros vosotras        -éis
ellos, ellas, Uds.          -án
