interesar — Spanish conjugation
to interest
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 | intereso | I interest |
| tú | interesas | you interest |
| vos | interesás | you interest |

| ellos/ellas/Uds. | interesan | they interest |
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.
