Here's a breakdown:
* Devait: This means "had to" in the past tense.
* Se réveiller: This means "to wake up".
Let's see some examples:
* J'ai dû me réveiller tôt ce matin. (I had to wake up early this morning.)
* Il devait se réveiller à 6 heures du matin pour le travail. (He had to wake up at 6 am for work.)
Other options:
* A dû se réveiller: This is another way to say "had to wake up," using the verb "avoir" instead of "devoir". It emphasizes the necessity of waking up.
Important note: The verb "se réveiller" is reflexive, meaning it takes the reflexive pronoun "se" before it.
