Indicative

Present (Presente) Regular

The present tense is the most versatile tense in Spanish. It covers actions happening right now, habitual actions, and even near-future plans. One form does the work of three English constructions.

Ella habla inglés — She speaks / is speaking English

PronounSpanish
voste oscurecés
él/ella/Ud.se oscurece

Preterite (Pretérito indefinido) Regular

Used for completed past actions with a defined endpoint — a single event, a series of events, or an action that interrupted another. Common with time expressions like ayer, el lunes, una vez.

Ella habló de ti ayer — She spoke about you yesterday

PronounSpanish
él/ella/Ud.se oscureció

Imperfect (Pretérito imperfecto) Regular

Describes ongoing or habitual past states — what things were like, background context, what used to happen. Contrasts with the preterite which marks completed events.

Cuando era niño vivía en Valencia — When I was a child I lived in Valencia

PronounSpanish
él/ella/Ud.se oscurecía

Conditional (Condicional) Regular

Expresses hypothetical actions, polite requests, and what would happen under certain conditions. Also used for reported speech about the future from a past perspective.

¿Podrías ayudarme? — Could you help me?

PronounSpanish
él/ella/Ud.se oscurecería

Future (Futuro) Regular

Expresses future actions, predictions, and probability about the present. Formed with the full infinitive as stem for most verbs. In spoken Spanish, ir a + infinitive is often preferred for near future.

Ella hablará en conferencia mañana — She will speak at the conference tomorrow

PronounSpanish
él/ella/Ud.se oscurecerá

Present perfect (Pretérito perfecto) Regular

A compound past tense linking a past action to the present moment — something that has happened and still feels recent or relevant. More common in Spain than Latin America where preterite is preferred.

Hoy he hablado con el jefe — Today I have spoken with the boss

PronounSpanish
yome he oscurecido
te has oscurecido
voste has oscurecido
él/ella/Ud.se ha oscurecido

te habías oscurecido
voste habías oscurecido
él/ella/Ud.se había oscurecido

Present subjunctive (Subjuntivo presente) Irregular

Used in subordinate clauses after expressions of desire, doubt, emotion, necessity, or impersonal statements. Triggered by a change of subject between the main and subordinate clause.

PronounSpanish
él/ella/Ud.se oscurezca

Imperfect subjunctive (-ra) (Subjuntivo imperfecto (-ra)) Regular

The past subjunctive used after past main verbs, in if-clauses with conditional, and for polite softening. The -ra form is more common in everyday speech than the -se form.

Si pudiera, lo haría — If I could, I would do it

PronounSpanish
él/ella/Ud.se oscureciera

Imperfect subjunctive (-se) (Subjuntivo imperfecto (-se)) Regular

The alternative past subjunctive form. Interchangeable with -ra in most contexts but slightly more literary or formal. Both forms are grammatically correct in all regions.

Si pudiese, lo haría — If I could, I would do it

PronounSpanish
él/ella/Ud.se oscureciese

Other forms

Present progressive (Presente progresivo) Regular

Emphasises that an action is happening right now at this very moment. Less common than in English since the present tense already covers ongoing actions in Spanish.

PronounSpanish

te estás oscureciendo
voste estás oscureciendo
él/ella/Ud.se está oscureciendo
nosotrosnos estamos oscureciendo
