Questions & Answers about Vous avez la solution, alors vous la lui donnez sincèrement.
Why is the order la lui instead of lui la?
When you have two object pronouns in French, the order depends on the grammatical person. If both pronouns are third person (like la referring to the solution and lui meaning to him or to her), the direct object (le, la, les) always comes before the indirect object (lui, leur). Therefore, it must be la lui.
Does lui in this sentence specifically mean to him, or could it mean to her?
It could be either. As an indirect object pronoun, lui is completely gender-neutral. You have to rely on the wider context of the conversation to know whether you are giving the solution to a man or a woman.
Could I use donc instead of alors in this sentence?
