The <u>indirect object</u> replaces the one who receives the verb. It can be replaced, if it is in the third person, "le" (singular) or "les" (plural); they can also be replaced by unstressed pronouns (me, se, te, nos, os).
When a direct object and an indirect object are joined, <u>the indirect object must be put first and then the direct object</u>. When a third person indirect object is added, put "se".
