The conditional is a verb mood used for actions that are not guaranteed to occur; often they are dependent on certain conditions. It is equivalent to "would" in English.
The Spanish past conditional (aka conditional perfect) is used to indicate an action that would have occurred in the past if a certain condition had been met.
The Spanish conditional progressive is very similar to its English counterpart (would be + -ing). In both languages, the conditional progressive expresses an action that would be in progress at a certain point in time.
The Spanish future perfect is used just like its English counterpart: to indicate an action that will have taken place before another action or point in the future.
The Spanish future progressive is very similar to its English counterpart (will be + -ing). In both languages, the future progressive expresses an action that will be in progress at a certain point in the future.
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."
The English gerund is the -ing form of the verb. In Spanish, it’s the –ndo form.
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!).
