Creíste

Creíste is the second-person singular preterite indicative form of the Spanish verb "creer," which translates to "to believe" or "to think." The preterite tense is used to describe completed actions in the past. Therefore, "creíste" specifically means "you believed" or "you thought" in a completed past action.

For example, if someone said "Tú creíste que llegaría a tiempo," it translates to "You thought you would arrive on time." This implies that the belief or thought was a specific event that occurred in the past and is now finished. It's distinct from the imperfect tense, which would describe ongoing or habitual actions in the past.

The verb "creer" itself is a common and versatile verb in Spanish, used in a wide range of contexts, from expressing opinions and convictions to stating suppositions and doubts. "Creíste" encapsulates this meaning within the framework of a singular, completed past action attributed to "you." It is a fundamental part of Spanish conjugation and is frequently encountered in spoken and written language.
