The imperative mood is used to give direct commands, instructions, requests, or advice to someone. They are always second-person (tú, vos, usted, ustedes) because they address someone directly.

Irregulars
Affirmative tú

Affirmative vos
ir often becomes andá (instead of “í” or “vé”)
ser remains sé (same as tú )
