One of the things I find most amusing about the medical profession is that once you’ve learned a bit of Greek and Latin it becomes not only transparent but even a bit pedestrian:

Etymology

Hyperemesis gravidarum is from the Greek hyper-, meaning excessive, and emesis, meaning vomiting, and the Latin gravidarum, the feminine genitive plural form of an adjective, here used as a noun, meaning “pregnant [woman]”. Therefore, hyperemesis gravidarum means “excessive vomiting of pregnant women”.

yep.
