I exchanged a few e-mails today with Dave Black about Greek verbal aspect. He has quoted me on his blog, and I’ve extracted the material for the jesusparadigm.com site, so there’s a permanent link. What I said wouldn’t make a full discussion, so it’s best to read it there in the full context.
My own background involves an MA in Religion, concentrating in Biblical and Cognate Languages, which was built on a BA in Biblical Languages. I’ve tutored a few people and taught Greek and Hebrew in churches from time to time, but this is not my profession. I have taken about 12 graduate hours of linguistics.
