...and what I thought your thread was going to ask:
Don't be surprised when you meet with older alums (at Founders Day, for instance) who pronounce it "Ksee." In my experience, almost every alum who was initiated before the '60s will say "Alpha Ksee Delta." Of course, this comes across sounding like "Alf*ck See Delta", which I suspect is why it fell into disuse.
