Various sources I've read (e.g., the Wikipedia entry on Klingon) say that Klingon has two moods: indicative and imperative. Maybe this is right. But what determines whether something is a mood? Does Klingon have an interrogative mood (bItlhutlhtaH'a' Are you drinking?)? What about an optative mood (bIQuchjaj May you be happy)? We know that we can create an irrealis with net jalchugh; is this a subjunctive mood? Or does a mood require an inflected verb? Do the qualification suffixes create a mood?

Basically, how does one determine what moods a language actually has, and can we apply this to Klingon?
