I understand that they were given the name 'Hittites'. My question is more on the subject of why that particular term was chosen. Did the original archaeologists who discovered the kingdom think it was the Biblical Hittite kingdom, so they named it that, but later it turned out not to be, but the name stuck?
I just don't see why they weren't named the 'Hattites' or something similar. JIM's explanation makes sense, that somehow the pronunciations got mixed up and it turned into 'Hittite'.
