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.
The Spanish imperfect subjunctive has two complete sets of conjugations. Although you only need to memorize and use one or the other, you still need to be able to recognize both.
There are about a dozen Spanish verbs which must be conjugated with an indirect object pronoun, such as gustar and importar. This grammatical construction does not exist in English, but it’s not difficult once you get used to it.
A verb is the action word in a sentence. It is the word that says what happens, discusses an action, or describes a state of being.
Ir is one of the most common and useful Spanish verbs and has irregular conjugations in most tenses and moods. Aller literally means "to go" and is required to create the near future.
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.”
Oír means "to hear" and is an irregular Spanish verb.
