They are those pronouns that can function as subjects, but also exert a verbal action. Basically, in its use it can be talking about two or more subjects, who are performing, at the same time, an action; for example: "I bought a nice pink dress" , in the sentence "me" would be the reflexive pronoun, which, as stated above, is naming the subject (conjugated in the first person), as well as announcing the action that he is performing himself, the verbal action is falling on himself.
It is widely used in everyday language, being more used as a method to make sentences shorter, to, somehow, make the conversation more fluid. For each conjugation depending on the person, there is an average of two to three pronouns per section, with a total of 5 being used. For the first person, "me" would be the pronoun for the singular, so "us" is the plural; Some examples are: "I took the trouble to check email, replacing Gillian," "expects me a busy day," "Angelina and I, we love putting on makeup," "Mike and I are going to party every weekend of week".
In the second person, on the other hand, he has the pronoun "te" for the singular and "se" for the plural, in addition to you and you; examples of its use are: "why are you leaving so early, Maria?", "You will stay with my sister, to enjoy more comfort", "You had as much fun as a free butterfly." For the third person there is only one reflexive pronoun: "se", and it works for all its members; for example: “he fell off his bicycle”, “she wanted to commit suicide”, “they just wanted to go”.
