Questions & Answers about No se acerquen a la vitrina.
Why does this sentence use acerquen instead of acercan?
Where does the qu in acerquen come from?
Why is se placed before the verb?
In negative commands (telling someone not to do something), pronouns like se must go directly between the no and the verb. If this were a positive command (telling someone to do it), the pronoun would be attached to the end of the verb instead, making it acérquense.
Why do we need the pronoun se at all?
