reforzar — Spanish conjugation
to reinforce, to bolster, to buttress
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
| Pronoun | Spanish | English |
|---|---|---|
| yo | refuerzo | I reinforce |
| tú | refuerzas | you reinforce |
| vos | reforzás | you reinforce |
| él/ella/Ud. | refuerza | he/she/it reinforces |
| nosotros | reforzamos | we reinforce |
| vosotros | reforzáis | you (pl.) reinforce |
| ellos/ellas/Uds. | refuerzan | they reinforce |
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
| Pronoun | Spanish | English |
|---|---|---|
| yo | reforcé | I reinforced |
| tú | reforzaste | you reinforced |
| vos | reforzaste | you reinforced |
| él/ella/Ud. | reforzó | he/she/it reinforced |

| ellos/ellas/Uds. | reforzaron | they reinforced |
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.
