To say ‘wake up’ in Spanish, you use the phrase ‘despertar’ or ‘despierta’.
‘Despertar’ is the infinitive form of the verb, which means ‘to wake up’. For example, you might say ‘Necesito despertar temprano mañana’ (I need to wake up early tomorrow).
On the other hand, ‘despierta’ is the imperative form used to give a command or tell someone to wake up. For example, you could say ‘Despierta, ya es hora de levantarse’ (Wake up, it’s time to get up).
Both forms are commonly used in everyday conversations, so it’s good to be familiar with them.
