Indicative

Present (Presente) Irregular

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

PronounSpanishEnglish

comienzasyou begin
voscomenzásyou begin
él/ella/Ud.comienzahe/she/it begins
nosotroscomenzamoswe begin
vosotroscomenzáisyou (pl.) begin
ellos/ellas/Uds.comienzanthey begin

Preterite (Pretérito indefinido) Irregular

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

PronounSpanishEnglish

comenzasteyou began
voscomenzasteyou began

Imperfect (Pretérito imperfecto) Regular

voscomenzabas
él/ella/Ud.comenzaba
