The imperative is a verb mood used to give a command, either affirmative (Go!) or negative (Don’t go!).
The imperfect tense is used to talk about a past action or state of being without specifying when it began or ended. It is often equivalent to “was ___-ing” in English.
The Spanish imperfect progressive is very similar to its English counterpart (was + -ing). In both languages, the imperfect progressive expresses an action that was in progress in the past when it was interrupted by another event.
The imperfect tense of the subjunctive mood is used to express the same subjectivity in Spanish as the present subjunctive, but in the past.
You can explain what will happen in the near future with the construction ir a + infinitive; for example, El avión va a aterrizar en dos minutos – “The plane is going to land in 2 minutes.”
The passive voice is used to focus on the person or thing performing the action or to focus on an action without identifying the performer.
The English past participle is the -ed form of the verb. In Spanish, it’s the –do form.
The past perfect, also called the pluperfect, is a verb tense that distinguishes between two related things that happened in the past, indicating which one occurred before the other.
The Spanish perfect infinitive indicates an action that occurred before the action of the main verb, but only when the subject of both verbs is the same. The perfect infinitive sounds awkward in English – we usually change it to another tense or reword the sentence completely.
