Conocer (to know) · Imperfect

By TutorLily Editorial Team · Last updated

Conocer in the Spanish imperfect (pretérito imperfecto) is: yo conocía, tú conocías, él/ella/usted conocía, nosotros/as conocíamos, vosotros/as conocíais, ellos/ellas/ustedes conocían. The imperfect of conocer keeps the static 'to know' meaning, in contrast with the preterite 'conocí' (met). 'Conocía a Juan' = 'I knew Juan (already, at that time)'. Conocer is fully regular in the imperfect.

Tip

Working with the imperfect

The imperfect paints the background of a past scene: weather, age, habits, descriptions, ongoing actions that get interrupted. "Era de noche" (it was nighttime), "tenía cinco años" (I was five years old), "iba al parque cuando me llamaste" (I was going to the park when you called me). Only three verbs are irregular in the imperfect — ser (era), ir (iba), and ver (veía). Every other Spanish verb is regular here, which makes the imperfect one of the easiest tenses to learn.

Questions

Frequently asked questions

How do you conjugate conocer in the imperfect?
Conocer is regular in the imperfect: yo conocía, tú conocías, él/ella/usted conocía, nosotros/as conocíamos, vosotros/as conocíais, ellos/ellas/ustedes conocían. The accent on 'í' is required in every form.
When do I use 'conocía' instead of 'conocí'?
Use 'conocía' for ongoing past familiarity — what you already knew during some past stretch of time: 'En 2020, ya conocía a Juan' (In 2020, I already knew Juan). Use 'conocí' for the moment of first meeting: 'Conocí a Juan en 2019' (I met Juan in 2019). The contrast is static familiarity (imperfect) vs the start of acquaintance (preterite).
How do I say 'when we met' vs 'when we knew each other'?
'Cuando nos conocimos' (preterite) = when we met (the moment of first acquaintance). 'Cuando nos conocíamos' (imperfect) = when we used to know each other / during the time we were acquainted. The reflexive 'conocerse' is the standard way to express mutual acquaintance: 'Juan y yo nos conocimos en 2019' (Juan and I met in 2019).
