Reflexive pronouns

Today, in my class, we started with the reflexive pronouns and my teacher taught me that they are a type of word and they are used for decribe reflexive actions.
In the sentence, the subject and the object coincide.

*We can see that in the plural forms the "-f" is changed by the suffix "-eves".

If it isn´t enough for you, here it´s a link about a video of the reflexive pronouns:

An other reflexive pronoun is each other that is used to talked about reciprocal actions.
           Ex: ·We sent each other Christmas cards.
                 ·Our friends were shouting at each other all night.
