That Darth is a title, not a name. I mean, why the hell not? First of all, it’s a solid portmanteau (“Dark Lord of the Sith”). Second of all, maybe this is just me, but I think Darth is kind of a funny name, but works fine as a title. Also, despite what people say, there is nothing in the OT that would suggest this shouldn’t be the case.

Disagree. At least in terms of how Obi-wan refers to him which suggests he was called Darth before he turned to evil and that was his first name. Before 1999 it didn’t show up as a title for any other EU characters. It just shows the total lack of imagination and writing skills George had when he scribbled out TPM.
