sentaste

Sentaste is the second-person singular preterite (past simple) indicative form of the Spanish verb sentar. It describes a completed action in which the subject tú seated someone or placed them in a chair or position. The related reflexive form te sentaste describes the action of sitting down oneself, as in te sentaste a la mesa. Sentar is a transitive verb, so its primary use is to cause someone to sit or to place someone in a position.

Usage and examples:

Ayer sentaste al niño en la silla. (Yesterday you seated the child in the chair.)

Anoche sentaste a los invitados junto a la mesa. (Last night you seated the guests around the table.)

In contrast, to express that you sat yourself down, Spanish typically uses te sentaste (you sat down), not sentaste.

Notes:

Sentaste is part of a regular -ar verb paradigm in the preterite: senté, sentaste, sentó, sentamos, sentasteis, sentaron. The form is mainly used when the action is directed by tú toward a person or object being seated. The related verb phrase sentar and its reflexive counterpart sentarse cover both transitive seating actions and the reflexive “sit down” sense, respectively, with appropriate pronoun placement depending on tense and mood.
