cerraste

Cerraste is the second-person singular preterite form of the Spanish verb cerrar, meaning "you closed." It is used to describe a completed action in the past performed by the informal subject tú. The form can refer to closing physical objects, such as doors or windows, or more abstract closures, like ending a session or a conversation.

In usage, cerraste appears in statements like "Ayer cerraste la puerta" and questions like "¿Cerraste las ventanas?" The preterite for -ar verbs follows the endings -é, -aste, -ó, -amos, -asteis, -aron, so cerraste is formed from the stem cerr- plus -aste. It is the standard past-tense form for tú for this class of verbs.

Cerraste is part of the first conjugation (-ar). In the present tense, the verb shows a stem change (cierro, cierras, cierra, cerramos, cerráis, cierran), but in the preterite there is no stem change: cerré, cerraste, cerró, cerramos, cerrasteis, cerraron.

Etymology: cerrar derives from Latin clausare or claudere, passing into Spanish through Old Spanish. Related forms include cierre (closing) and cerrado (closed). The word family centers on the concept of shutting or sealing something, whether physical or figurative.
