filtrar — Spanish conjugation
to filter
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 | English |
|---|---|---|
| yo | filtro | I filter |
| tú | filtras | you filter |
| vos | filtrás | you filter |
| él/ella/Ud. | filtra | he/she/it filters |

| vosotros | filtráis | you (pl.) filter |
| ellos/ellas/Uds. | filtran | they filter |
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 | English |
|---|---|---|
