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 fundo
te fundas
voste fundás
él/ella/Ud.se funda
nosotrosnos fundamos
vosotrosos fundáis
ellos/ellas/Uds.se fundan

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 fundé
te fundaste
voste fundaste
él/ella/Ud.se fundó
nosotrosnos fundamos
vosotrosos fundasteis
ellos/ellas/Uds.se fundaron

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 fundaba
te fundabas
voste fundabas
él/ella/Ud.se fundaba
nosotrosnos fundábamos
vosotrosos fundabais
ellos/ellas/Uds.se fundaban

te fundarías
voste fundarías
él/ella/Ud.se fundaría
nosotrosnos fundaríamos
vosotrosos fundaríais
ellos/ellas/Uds.se fundarían

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.

él/ella/Ud.se fundará
nosotrosnos fundaremos
vosotrosos fundaréis

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 fundado
te has fundado
voste has fundado
él/ella/Ud.se ha fundado
nosotrosnos hemos fundado
