contagiarse — Spanish conjugation
to become infected
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 contagio |
| tú | te contagias |
| vos | te contagiás |
| él/ella/Ud. | se contagia |
| nosotros | nos contagiamos |
| vosotros | os contagiáis |
| ellos/ellas/Uds. | se contagian |
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 contagié |

| vosotros | os contagiasteis |
| ellos/ellas/Uds. | se contagiaron |
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.
