thermae f pl (genitive thermārum); first declension[1]

Etymology

It is borrowed from Ancient Greek θέρμαι (thérmai, “hot springs”),[1][2] the plural of the Greek adjective θερμός (thermós, “warm”) used as a noun.[3][4] Lewis & Short explain it as short for aquae, the same as Greek “warm waters”.[5] Köbler takes the Greek word back to Proto-Indo-European *gʷʰer- (“hot, warm”).[4]

Earliest recorded meaning

Cicero has Thermae only as the name of a town in Sicily with warm baths.[5][3] As a common noun, “hot baths”, Georges and Lewis & Short cite Seneca first.[3][5]

Semantic evolution

It names the hot baths of Rome, usually a public building with gymnasiums and other amenities: Pliny the Elder mentions the baths of Agrippa, Martial those of Nero.[1][5] Juvenal uses it for a shop selling hot drinks, a thermopolium.[5][3] Church Latin keeps both baths and hot springs.[6] In British medieval Latin it is a natural hot spring, hot water, and a bath or bathing complex, as at Bath.[7]
