deberse — Spanish conjugation
to be due to (deberse a)
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
| Pronoun | Spanish |
|---|---|
| yo | me debo |
| tú | te debes |
| vos | te debés |
| él/ella/Ud. | se debe |
| nosotros | nos debemos |
| vosotros | os debéis |
| ellos/ellas/Uds. | se deben |
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
| Pronoun | Spanish |
|---|---|
| yo | me debí |
| tú | te debiste |
| vos | te debiste |
| él/ella/Ud. | se debió |
| nosotros | nos debimos |
| vosotros | os debisteis |
| ellos/ellas/Uds. | se debieron |
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.
