vertex --> vertices
matrix --> matrices
vortex --> vortices
complex --> complexes
I don't see the pattern. It's not -ix versus -ex, so is there a rule (or at least linguistic explanation) for why some words take ces and some words take xes?

Jesse Williams is on the right track. I've had 8 years of Latin, and the problem lies with the evolution of a language. The Internet has caused English to evolve (some would say become corrupted) at the fastest rate it has ever had.
So, what is "correct" now depends on common usage and ultimate what the folks at M&W think is time to add to their dictionary, unfortunately...
BTW, from my classical education, it is 'prefixes' and 'mutices' which are correct. Just because that is how they ended up being used for many decades (or longer).
