Forming and Using the Reflexive Verbs

Reflexive verbs indicate that the subject of an action is also the object that receives the action, that is to say, the subject and the object are the same. Reflexive verbs can be described as having a mirror effect; the action performed by the subject “reflects” back to the subject. Whatever the subject does, the subject feels.

Compare these two sentences:

--Yo me lavo. I wash myself.
Lavarse is a reflexive verb.
