conoscevi

Conoscevi is the Italian verb form used as the second-person singular imperfect indicative of conoscere, meaning "you knew" or "you used to know." The imperfect expresses a past state, ongoing knowledge, or habitual acquaintance with a person or thing.

Etymology and grammar: conoscere comes from Latin cognoscere. It is a transitive verb that takes a direct object to express acquaintance or knowledge. In the imperfect tense, the endings follow the regular pattern for -ere verbs: io conoscevo, tu conoscevi, lui conosceva, noi conoscevamo, voi conoscevate, loro conoscevano. Therefore, conosi o giuste? The form relevant to you in the past is conoscevi.

Usage: Conoscevi is used to describe past knowledge or familiarity, whether with a person, place, or fact. It can mark habitual knowledge or a state that existed over a period in the past. It is often accompanied by time expressions or memory cues.

Examples:

- Quando eri bambino, conoscevi già quel paese. (When you were a child, you already knew that town.)

- Conoscevi Maria da molto tempo. (You had known Maria for a long time.)

- Non conoscevi ancora la verità. (You did not yet know the truth.)

Note that conoscere has other tenses and moods in Italian, and the same verb follows regular -ere conjugation patterns in the imperfect, including conoscevi for the second person singular.
