| | When to use what subjunctive in Spanish |
 | | The simple tenses of the indicative are the present [hablo], future [hablaré], imperfect [hablaba], and preterit [hablé]; the simple tenses of the subjunctive are the present [hable] and imperfect [hablara] tenses. |
 | | When a governing verb in the present, future, or future perfect tense and the subjunctive is required in a subordinate clause, use the present or present perfect subjunctive; with a governing verb in a past time tense imperfect, preterit, past perfect, conditional, or conditional perfect, use only a past time subjunctive: imperfect or past perfect. |
 | | In either case the simple subjunctive tense (present for present time, or imperfect for past time) is used to express a simultaneous or future action, and the perfect tense (present perfect for present time, or past perfect for past time) is used to indicate a previous activity. |
