AR Verbs in the Future Tense
AR, ER and IR Verbs have the same set of endings in the Future Tense. To form the future tense with AR verbs, do not remove the infinitive ending and add the future endings. Here is the example with 'hablar':

Hablaré - I will talk

Hablarás - you will talk

Hablará - he/she will talk / you will talk (formal)

Hablaremos - we will talk

Hablaréis - you will talk (plural)

Hablarán - they will talk / you will talk (formal plural)
