That's right:
Chondropterygian is an
adjective meaning "
Having a
cartilaginous skeleton" or a
noun meaning "
One of the
Chondropterygii (a
group of
fishes)".
And not, as was formerly thought, another nickname for the Bronx, or slang euphemism for one-legged accountant.
I really wish there were an easier way to add links to webster's writeups.
