Quejasteis

"Quejasteis" is the second-person plural (vosotros/vosotras) preterite indicative form of the Spanish verb *quejarse*, which means "to complain" or "to grumble." This conjugation is used in Spanish-speaking regions where the *vosotros* form is standard, primarily in Spain and some parts of Latin America.

The verb *quejarse* is a reflexive verb, meaning the subject performs the action on themselves. Its conjugation follows the standard reflexive pattern, where the pronoun *os* (yourselves) is attached to the verb. In the preterite tense, the base form of the verb changes to *quejá-* before adding the ending *-steis*, resulting in *quejasteis*.

For example:

- "Vosotros os quejasteis de la comida" translates to "You all complained about the food" (Spain).

- "Quejarse" can also imply expressing dissatisfaction or pain, such as "quejarse de un dolor" (to complain about pain).

The preterite tense (*quejasteis*) is used to describe completed actions in the past, emphasizing the beginning or end of an event. It contrasts with the imperfect tense (*os quejabais*), which would describe ongoing or habitual actions in the past.

This conjugation is part of the broader Spanish verb system, where subject pronouns often clarify meaning, especially in informal contexts. While *vosotros* is fading in some Latin American dialects in favor of *ustedes*, it remains widely used in Spain and certain regions like parts of Central America.
