I had to look it up: it's pronounced "cee omega" according to Wikipedia.

That's also evident from the URL: comega_startpage.htm

I pronounced it co-mega in my head. But c-omega makes more sense.

I look at those two symbols, and in my head I hear "cow". I know there's only a C and a W, but my brain doesn't care. Maybe it's 'cause the W is kinda roundish? Anyways. "Cow".

My former ancient Greek teacher would want me to point out that this is a lowercase Omega (=a long "o" in Greek). So yes, it even sounds kinda like the first part of cow! ;-)
