Answer:
The answer is Reflexive Pronoun
Step-by-step explanation:
In Spanish there are reflexive verbs and reflexive pronouns. A reflexive verb indicates that the action is performed on the subject themselves, in other words, it indicates that someone or something is performing an action on or for itself. For example, the verb despertarse is reflexive, and means To wake oneself up. Reflexive verbs are formed by adding the reflexive pronoun "se" at the end of the verb in infinitive form. i.e. despertar-se (to wake oneself up), lavar-se(to clean oneself up) , levantar-se (to get oneself up), vestir-se (to get dressed), etc...
Now, when we conjugate one of these verbs with the different pronouns, we add the Reflexive Pronoun before the verb. The reflexive pronouns for each personal pronoun are:
Subject Reflexive Pronoun
Yo Me
Tu Te
Él/Ella Se
Nosotros Nos
Usted/ Ustedes Se
Ellos/Ellas Se
So in this case, the reflexive verb is ponerse (to put on), and if we conjugate it it would be
Yo me pongo
Tu te pones
Él/ella se pone
Nosotros nos ponemos
Usted se pone
Ustedes se ponen
Ellos/Ellas se ponen
Now, if we turn in into a negative command, we add "No" at the beginning,
and the Indirect Object Pronoun "Los" to refer to the object they're talking about. "No se los ponga" would translate to "Don´t put them on". "Los" is referring to whatever object the person "can´t" put on.
