In Spanish there are two main future tenses. The first being the Informal Future which in English would be 'I am going', and the other being the Simple Future which in English would be 'I will'.The structure of the Informal Future goes as follows: The verb IR + A + INFINITIVE. For example, I am going to go - Voy (first person conjugation of IR) + A + IR. Another example would be: She is going to do her homework - Vas a hacer sus deberes. The main thing to know for the tense is the conjugation of the verb 'ir' which goes as follows - Voy, Vas, Va, Vamos, Vais, Van.The structure of the Simple Future goes as follows: You should keep the infinitive the same and add the ending on relating to which person you're talking about. For example, with the verb Comer, to form it in the first person Simple Future, it would be Comeré (I will eat)The endings go as follows - é, ás, á, emos, éis, án and the endings remain the same regardless of whether the verb is an AR, ER or IR.A final example would be- 'We will talk to my mum' - Hablaremos a mi madre.
