explicaste

Explicaste is the second-person singular preterite tense form of the Spanish verb explicar. It translates as "you explained" and is used when referring to a past action in which someone explained something to another person. The form is used with the informal singular subject tú, or with an understood tú in conversation.

Origin and formation: explicar comes from Latin explicare, meaning "to unfold or explain." In the preterite, -ar verbs for tú end with -aste, producing explicaste. The word carries no accent in standard Spanish.

Usage: Explicaste appears in narratives or descriptions of past events. In formal contexts, la forma de usted es explicó. The corresponding forms for other persons are explico, explicas, explica, explicamos, explicasteis, explicaron.

Examples: Ayer explicaste cómo funciona el sistema. ¿Explicaste tú la tarea al grupo? These examples illustrate how the form fits into questions or statements about past explanations directed at another person.
