Learn Spanish (Spain): ¿Qué compráis en la tienda?

compráis is the plural "you all" form, used in Spain when speaking informally to a group of people. If you were asking just one person, you would use compras. Both are present tense forms of the regular verb comprar (to buy).

Where is the word for "you" in this sentence?

Spanish often drops the subject pronoun because the verb ending already tells you who is doing the action. The -áis ending on compráis specifically means "you all" (vosotros), so the pronoun itself is not needed.

Why does compráis have an accent mark on the 'a'?

In the present tense, the vosotros form for all regular -ar verbs ends in -áis with a written accent. This shows you that the spoken emphasis belongs on that syllable.

Why does Qué have an accent mark?

All question words in Spanish, like Qué (What), Cómo (How), and Dónde (Where), carry a written accent. This distinguishes them from similar words used in regular, non-question sentences.
