Also, the Complete Wordfinder is about three inches thick, so if the word existed it would definitely be in there.

I have looked up the meaning of the word "threatened" in the Oxford Complete Wordfinder and this is what it says: Put at risk/jeopardy, harrassed, terrorized, bullied, endangered, cautioned, warned of, intimidated; to have a threat made against a person; to tell a person that they will be harmed.
