hydrophobia f (genitive hydrophobiae); first declension[1]
Etymology
It is borrowed from Ancient Greek ὑδροφοβία (hudrophobía, “dread of water”),[1][2][3] from ὑδροφόβος (hudrophóbos, “dreading water”), from ὕδωρ (húdōr, “water”) and φόβος (phóbos, “fear”).[4]
Earliest recorded meaning
Caelius Aurelianus discusses it in his work on acute diseases.[2][5] Köbler dates him to the 5th century AD.[3]
Semantic evolution
It was dread of water, the hydrophobia that marks rabies.[2][6] Celsus still writes the word in Greek, and Ovid describes it in Latin as formīdātae aquae, “water that is dreaded”.[2][5]
In medieval Latin it was a morbid fear of water and rabies itself.[7][6] An Old English gloss renders it as “water-fear”.[7] English hydrophobia is recorded in the late 14th century.[4]
Timeline
- 14–37 AD – Celsus writes the word as Greek.[2][3]
- 5th century AD – Caelius Aurelianus uses it.[2][3]
- late 14th century – English hydrophobia is recorded.[4]
