How to use each tense

Each tense below explains when to use it with prometer, with one example sentence. The example forms are taken from the tables above.

Present indicative

The present tense talks about what happens now, habits, routines and general truths. It is the first tense every learner needs, because it covers daily life: what you do, what you like, where you live. For most verbs the present is also the base for the present subjunctive, so learning it well pays off twice.

This tense is regular for this verb — the endings follow the standard pattern for its verb class.

Example: Yo prometo ayudar.

Preterite (past)

The preterite talks about finished actions in the past — things that started and ended at a specific moment. Use it for events, for what happened yesterday, last year, or at a particular time. It answers the question "what happened?" and it is the tense of stories told as a sequence of events.

This tense is regular for this verb — the endings follow the standard pattern for its verb class.

Example: Ayer yo prometí ayudar.

Imperfect (past)

The imperfect talks about the past as background: habits, repeated actions, descriptions, and things that were in progress when something else happened. Use it for "used to", for setting a scene, and for age, time and weather in the past. It answers "what was going on?" rather than "what happened?".

This tense is regular for this verb — the endings follow the standard pattern for its verb class.

Example: En aquella época, yo prometía ayudar.

Future

The future tense talks about what will happen: plans, predictions and promises. In everyday speech Spanish speakers often use "ir a + infinitive" instead, but the future tense is essential for formal writing, for promises, and for guessing about the present ("¿Dónde estará?").

This tense is regular for this verb — the endings follow the standard pattern for its verb class.

Example: Mañana yo prometeré ayudar.

Conditional

The conditional talks about what would happen: hypothetical situations, polite requests, and advice. It pairs with the imperfect subjunctive in "if" sentences ("Si pudiera, lo haría"). It is also the polite way to ask for things and to soften opinions.

This tense is regular for this verb — the endings follow the standard pattern for its verb class.

Example: Yo prometería ayudar si pudiera.

Present perfect

The present perfect (haber + past participle) talks about the recent past and about experience: what you have done, what has just happened, what you have never tried. It connects the past to the present moment, so it often appears with "hoy", "esta semana", "ya" and "todavía no".

This tense is regular for this verb — the endings follow the standard pattern for its verb class.

Example: Yo ya he prometido ayudar.

Pluperfect

The pluperfect (había + past participle) talks about the past before the past: what had already happened when something else happened. Use it to order two past events — the pluperfect one comes first in time. It appears constantly in stories and explanations.

This tense is regular for this verb — the endings follow the standard pattern for its verb class.

Example: Yo ya había prometido ayudar antes.

Future perfect

The future perfect (habré + past participle) talks about something that will already be finished by a future moment: "Para mañana ya habré terminado". It is also used to guess about the past: "¿Dónde habrá ido?". It is less common in speech but regular in writing.

This tense is regular for this verb — the endings follow the standard pattern for its verb class.

Example: Para mañana yo ya habré prometido ayudar.

Conditional perfect

The conditional perfect (habría + past participle) talks about what would have happened: the past of the conditional. It appears in "if" sentences about a past that did not happen ("Si hubiera sabido, habría venido") and in polite regrets and reproaches.

This tense is regular for this verb — the endings follow the standard pattern for its verb class.

Example: Yo habría prometido ayudar si hubiera podido.

Present subjunctive

The present subjunctive is the mood of wishes, doubts, emotions and influence: what you want, hope, doubt or demand. It appears after "quiero que", "espero que", "es posible que", "ojalá" and after verbs of emotion and doubt. It never stands alone — a trigger in the main clause calls for it.

This tense is regular for this verb — the endings follow the standard pattern for its verb class.

Example: Espero que él prometa ayudar.

Imperfect subjunctive (-ra)

The imperfect subjunctive is the past of the subjunctive: it follows past-tense triggers ("Quería que vinieras") and it is the tense of "if" clauses about unlikely or impossible situations ("Si tuviera dinero, viajaría"). The -ra forms shown here are the standard ones; -se forms exist too but -ra is far more common in speech.

This tense is regular for this verb — the endings follow the standard pattern for its verb class.

Example: Si él prometiera ayudar, sería perfecto.

Imperative (affirmative)

Affirmative commands tell someone to do something: "¡Ven aquí!", "¡Siéntate!". The tú and vosotros forms are the ones you will use most, and they are also the ones that break the regular pattern most often — the tú affirmative command comes from the él/ella present form, not from the infinitive.

This tense is regular for this verb — the endings follow the standard pattern for its verb class.

Example: ¡Promete ayudar!

Imperative (negative)

Negative commands tell someone not to do something: "¡No hables!", "¡No te vayas!". Unlike affirmative commands, negative commands always use the subjunctive forms, for every person. If you know the present subjunctive, you already know the negative imperative.

This tense is regular for this verb — the endings follow the standard pattern for its verb class.

Example: No prometas ayudar.

Common mistakes

The errors learners actually make with prometer — and how to fix them.

  • Wrong: *Yo prometí ayudar — learners often write prometi without the accent. → Right: Yo prometí ayudar.. The preterite yo form is prometí, with an accent on the final i. Prometer is regular, so the accent is the only spelling point.
  • Wrong: *Te prometo que ayudo — after prometer que, the second verb takes the future or the present, not a bare present for a future promise; Te prometo que ayudaré is clearer. → Right: Te prometo que prometeré.. After prometer que, use the future for a promise about tomorrow: Te prometo que ayudaré. The present (ayudo) can sound like a statement about now.
  • Wrong: *Espero que tú prometes ayudar. → Right: Espero que tú prometas ayudar.. After espero que, use the subjunctive prometas, not the indicative prometes.
  • Wrong: *Yo he prometido ayudar — learners sometimes write he prometo instead of the participle. → Right: Yo he prometido ayudar.. The perfect tenses use the participle prometido after haber: he prometido, not he prometo.
