The imperfect tense of regular -ar verbs

Spanish uses the imperfect tense to talk about ongoing past actions, background descriptions, and past habits (things you "used to" do or "would" do repeatedly).

Also, pay close attention to the nosotros/nosotras form: it always has an accent mark on the first a of the ending.

Nosotros inventábamos reglas tontas para el juego.
