The future subjunctive is supposed to be used in Spanish when a verb or expression requiring the subjunctive in the main clause is in the present or future and refers to a future action.
The future tense is used for upcoming events. It is usually translated as "will."
There are a number of Spanish verbs which are regular in all but the first person singular. These are known as “g verbs” or “yo go verbs” because the first person singular requires an unexpected g.
The English gerund is the -ing form of the verb. In Spanish, it’s the –ndo form.
The Spanish verb haber has irregular conjugations.
Hacer – to do or to make – is irregular in the first person singular.
Hacer, which literally means "to do" or "to make," is found in a number of idiomatic expressions. One of this verb’s most important uses has to do with expressing time.
Several dozen verbs require a reflexive pronoun but are neither reflexive nor reciprocal. These verbs use the reflexive pronoun to create a meaning different from (though often related to) the meaning of their non-pronominal siblings.
The imperative is a verb mood used to give a command, either affirmative (Go!) or negative (Don’t go!).
The Spanish imperative exists for 5 different grammatical people, and two of those have different conjugations for affirmative and negative imperatives.
