Reflexive verbs are verbs that end in "-se" and indicate that the subject is performing the action to themselves. Some examples of reflexive verbs are despertarse (to wake up), acostarse (to go to bed), and ducharse (to take a shower). Reflexive verbs use reflexive pronouns like me, te, se before the conjugated verb. The structure is subject + reflexive pronoun + conjugated verb. Common reflexive pronouns are yo me, tú te, él se, ella se, and nosotros nos.
