In Spanish, there are two ways of forming the future tense. The first involves adding endings to the verb, and corresponds to ‘I will do’ or ‘I will go’ etc. in English.
The second way uses the verb ‘ir’ (to go), ‘a’ (to) and the infinitive of the verb to make something a lot like ‘I’m going to do’ or ‘I’m going to go’.
To talk about the future the first way, the following endings are added to the end of the infinitive verb for each pronoun:
Yo – é
Tú – ás
Él/Ella – á
Nosotros/Nosotras – emos
Vosotros/Vosotras – éis
Ellos/Ellas – án
However, there are some irregular verbs that change slightly before the endings are added on, for example:
Hacer ( to do) – Haré (I will do)
Querer (to want) – Querré ( I will want)
Venir (to come) – Vendré ( I will come)
Tener (to have) – Tendré (I will have)
Poner ( to put) – Pondré (I will put)
Valer ( to be worth) – Valdrá ( It will be worth)
Poder (to be able to) – Podré (I will be able to)
Caber ( to fit in) – Cabrá ( It will fit in)
Haber ( to have/exist) – Habrá ( There will be)
Saber ( to know) – Sabré ( I will know)
Decir ( to say/tell) – Diré ( I will say)
The second way to make the future tense is slightly easier and involves conjugating the verb ‘ir’ in the present tense:
The Preposition ‘a’ (to) and the infinitive go after this:
Voy a hacer – I’m going to do.
Some example sentences:
Vamos a hacerlo más tarde – We’re gonna do it later.
Voy a decírselo – I’m going to tell him.
Podrás hablar español muy pronto – You’ll be able to speak Spanish very soon.
Jugarás para el equipo nacional – You’ll play for the national team.
Podremos ir mañana – We’ll be able to go tomorrow.
Hope that made sense 🙂
