To effectively use French object pronouns, you need to understand what they mean and where they go in the sentence. In the affirmative imperative, direct-object pronouns (like reflexive pronouns) follow the verb and are attached to it with hyphens; in addition, me changes to moi and te changes to toi. This chart shows the object pronoun word order with the affirmative imperative (command):

Direct Object (3rd Person) Direct Object (1st or 2nd Person) or Reflexive Pronoun Y (there — refers to place) En (some, any, of them)
Le moi y en
La toi
Les lui
nous
vous
leur

Here’s the word order with everything else, including the negative imperative:

Reflexive Pronoun, Direct Object (1st or 2nd Person), or Indirect Object (1st or 2nd Person) Direct Object (3rd Person) Indirect Object (3rd Person) Y (there — refers to place) En (some, any, of them)
me le lui y en
te la leur
se les
nous
vous
