Using pronouns with commands

When object and reflexive pronouns are used with affirmative commands, they are always attached to the verb. When used with negative commands, the pronouns appear between no and the verb

Levántense temprano. - Wake up early. Dime todo. - Tell me everything. No se levanten tarde. - Don't wake up late. No me digas nada. - Don't tell me anything.

When the pronouns nos or se are attached to an affirmative nosotros/as command, the final s of the command form is dropped.

Sentémonos aquí. - Let's sit here. No nos sentemos aquí. - Let's not sit here. Démoselo mañana. - Let's give it to him/her tomorrow. No se lo demos mañana. - Let's not give it to him/her tomorrow.
