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
yome uno
te unes
voste unís
él/ella/Ud.se une
nosotrosnos unimos
vosotrosos unís
ellos/ellas/Uds.se unen

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
yome uní
te uniste
voste uniste
él/ella/Ud.se unió
nosotrosnos unimos
vosotrosos unisteis
ellos/ellas/Uds.se unieron

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
yome unía
te unías
voste unías
él/ella/Ud.se unía
nosotrosnos uníamos
vosotrosos uníais
ellos/ellas/Uds.se unían

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
yome uniría
te unirías
voste unirías
él/ella/Ud.se uniría
nosotrosnos uniríamos
vosotrosos uniríais
ellos/ellas/Uds.se unirían

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
yome uniré
te unirás
voste unirás
él/ella/Ud.se unirá
nosotrosnos uniremos
vosotrosos uniréis
ellos/ellas/Uds.se unirán

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 unido
te has unido
voste has unido
él/ella/Ud.se ha unido
nosotrosnos hemos unido
vosotrosos habéis unido
ellos/ellas/Uds.se han unido

Pluperfect (Pretérito pluscuamperfecto) Regular

The past of the past — describes an action that was already completed before another past event happened. Always implies a reference point in the past.

Ya había hablado cuando llegaste — She had already spoken when you arrived

PronounSpanish
yome había unido
te habías unido
voste habías unido
él/ella/Ud.se había unido
nosotrosnos habíamos unido
vosotrosos habíais unido
ellos/ellas/Uds.se habían unido

Conditional perfect (Condicional perfecto) Regular

Expresses what would have happened — actions that were possible but did not occur, or regrets about the past. Formed with conditional of haber + past participle.

Habría hablado, pero no me dejaron — I would have spoken, but they did not let me

PronounSpanish
yome habría unido
te habrías unido
voste habrías unido
él/ella/Ud.se habría unido
nosotrosnos habríamos unido
vosotrosos habríais unido
ellos/ellas/Uds.se habrían unido

Future perfect (Futuro perfecto) Regular

Describes an action that will have been completed by a certain point in the future, or expresses probability about a recent past action.

PronounSpanish
yome habré unido
te habrás unido
voste habrás unido
él/ella/Ud.se habrá unido
nosotrosnos habremos unido

Subjunctive

Present subjunctive (Subjuntivo presente) Regular

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.

Espero que hable — I hope she speaks

PronounSpanish
yome una
te unas
voste unas
él/ella/Ud.se una
nosotrosnos unamos
vosotrosos unáis
ellos/ellas/Uds.se unan

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
yome uniera
te unieras
voste unieras
él/ella/Ud.se uniera
nosotrosnos uniéramos
vosotrosos unierais

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

PronounSpanish
yome uniese
te unieses
voste unieses

PronounSpanish
yome haya unido
te hayas unido
voste hayas unido
él/ella/Ud.se haya unido
nosotrosnos hayamos unido
vosotrosos hayáis unido
ellos/ellas/Uds.se hayan unido

Pluperfect subjunctive (Pluscuamperfecto de subjuntivo) Regular

Expresses what had happened in hypothetical or unreal past contexts — the subjunctive equivalent of the pluperfect. Common in contrary-to-fact past conditions.

Si hubiera hablado, lo habrían creído — If she had spoken, they would have believed her

PronounSpanish
yome hubiera unido
te hubieras unido
voste hubieras unido
él/ella/Ud.se hubiera unido
nosotrosnos hubiéramos unido
vosotrosos hubierais unido
ellos/ellas/Uds.se hubieran unido

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.

te estás uniendo
voste estás uniendo
él/ella/Ud.se está uniendo
nosotrosnos estamos uniendo
vosotrosos estáis uniendo

yome estuve uniendo

vosotrosos estuvisteis uniendo
ellos/ellas/Uds.se estuvieron uniendo

yome estaría uniendo
te estarías uniendo
voste estarías uniendo
