> When Klingon is spoken
Indeed, this is the important point here: "when klingon is spoken".
Before starting this thread, while contemplating this matter, I asked myself: "If klingons actually existed, and heard a single noun with the voice of the speaker being colored as if there was an {-'a'} attached to it, then wouldn't he understand it (the noun) as a question ?
Since during speech, the voice in Klingon is "colored" (I'm using the word we use in Greece, because I don't know the english word), as it is in english (to express anger/frustration/sadness), then probably a noun followed by a question mark, would probably be understood in Klingon as being a question.
However, I agree that this is something that would mainly take place in informal spoken speech.
