I am saying... Put them to bed at 9:00.

I don't know wether to use leurs or Les.

I have Mets-leur au lit a 9h00. Is it indirect or direct because if it is direct I think I would use Les but idk if it is.

Looks like Mme Sra is not online tonight. She will most probably give a detailed answer when she gets on.

To answer your question quickly, "mettre quelqu'un au lit" is transitive direct.

You could also say "coucher les enfants" to mean the same thing. It is also transitive direct.

Do not forget the accent in "à 9h".

For direct objects, you use "le/la/les", meaning "him/her/it/them", depending on the gender and number of the object you're replacing. This pronoun goes right before the conjugated verb in your sentence.

Ex: "Je le/la prends tous les jours." (I take it everyday)).
Ex: "Je les prends tous les jours." (I take them everyday).

For indirect objects, you use "lui", meaning "(to) him/her" or "leur" meaning "(to) them." These also go directly before the conjugated verb in your sentence.
Ex: "Je lui donnerai le livre demain." (I will give the book to him tomorrow).
Ex: "Je leur donnerai le livre demain." (I will give the book to them tomorrow).

Thus “Mets les au lit “(direct object)

I must say, that in affiramtive imperative sentences the object pronoun follows the verb.

"Mets les au lit à 9h."

To determine whether to use "leurs" or "les" in the sentence "Put them to bed at 9:00," you need to consider if the pronoun is used as a direct or an indirect object.

In this sentence, the pronoun is used as an indirect object because it indicates to whom the action of putting to bed is done. "Them" refers to a group of people, implying multiple individuals. However, since there is no specific information about these individuals, we use "leur" as the indirect object pronoun. "Leur" is the plural form of the indirect object pronoun and it is used to represent "to them" in French.

Therefore, the correct sentence is: "Mets-leur au lit à 9h00."

Remember that if you are referring to a specific group of people with a known masculine plural noun as the antecedent, you would use "les" as the direct object pronoun. For example, if you were referring to a specific group of boys, you would say "Mets-les au lit à 9h00."
