Conocer (to know) · Preterite

By TutorLily Editorial Team · Last updated

Conocer in the Spanish preterite (pretérito indefinido) is: yo conocí, tú conociste, él/ella/usted conoció, nosotros/as conocimos, vosotros/as conocisteis, ellos/ellas/ustedes conocieron. The preterite of conocer often means 'met' (for the first time) rather than 'knew'. 'Conocí a Juan en la universidad' = 'I met Juan in college'. This is part of the meaning-shift preterite family alongside saber (found out), poder (managed to), and querer (tried to).

Tip

Working with the preterite

The preterite describes a finished past action with a clear boundary — "ayer comí pizza" (yesterday I ate pizza). The key contrast is with the imperfect, which describes ongoing or repeated past actions without a defined endpoint. If you can substitute "used to" or "was doing" in English, you usually want the imperfect; if the action is one-and-done, you want the preterite. The irregular preterites (fui, hice, dije, tuve, vine, supe) are the highest-frequency in Spanish — front-load them.

Questions

Frequently asked questions

How do you conjugate conocer in the preterite?
Conocer is regular in the preterite: yo conocí, tú conociste, él/ella/usted conoció, nosotros/as conocimos, vosotros/as conocisteis, ellos/ellas/ustedes conocieron. The 'c→zc' irregularity of the yo form doesn't appear here — preterite endings start with vowels other than 'o', so no orthographic shift is needed.
Why does 'conocí' mean 'I met' instead of 'I knew'?
Conocer is one of the four classic meaning-shift preterite verbs: saber (found out), conocer (met), poder (managed to), querer (tried to). The imperfect 'conocía' keeps the static 'knew' meaning. The preterite 'conocí' marks the moment of first acquaintance: 'lo conocí en 2019' = I met him in 2019 (for the first time). This contrast is one of the highest-leverage past-tense pedagogy points.
Should I use 'conocí' (preterite) or 'conocía' (imperfect)?
Use 'conocí' for the moment of first acquaintance: 'Conocí a Juan en 2019' (I met Juan in 2019). Use 'conocía' for ongoing past familiarity: 'En 2020 ya conocía a Juan' (In 2020 I already knew Juan). The contrast is the start of acquaintance (preterite) vs the static state of being acquainted (imperfect). 'Conocía a Juan cuando me llamó' = I already knew Juan when he called me.
