I also remember something about the meaning of goat changing a few hundred years back. Mainly due to science excluding sheep from the definition. But i've no idea where I heard that. Likely on eons. Glass used to refer to a volcanic process that created clearing stone. The current man-made product def did not exist. But the volcanic stuff is still called glass. So yeah, that one likely counts as expanded rather than evolved.

I'll give you a freebie. Cloud has not really changed its meaning since the Norman conquest.
