Which is correct? It was she. OR It was her. It concerned him (or he). It concerned him (or he) who was lost.
> It was she. OR It was her. It was her. You can only have one subject in your sentence, and word order tells us it's It. > It concerned him (or he). Him. Objective pronoun. Direct object of the verb to concern. > It concerned him (or he) who was lost. Him. Same reason as above. A bit messy this though.
