Reflexive pronouns in Spanish are used when the subject and the object of a sentence are the same. For example:
I wash myself.
He brushes his teeth.
The cat licks itself.
We feed ourselves.
Reflexive pronouns work the same was as the other object pronouns, and in fact, are almost exactly the same as direct or indirect object pronouns. Like the difference between the direct and indirect object pronouns, the only difference between the reflexive pronouns and the other two is in the el/ella and ellos form. Let’s take a look:
|se||himself, herself, yourself, itself|
So in Spanish, our example sentences above would be:
Yo me lavo.
El se cepilla los dientes.
El gato se lame.
Nosotros nos alimentamos.
