Forms
aquāticus (feminine aquātica, neuter aquāticum); first/second-declension adjective[1]
Etymology
It is formed from Latin aqua (“water”) + -āticus.[2][3] The noun aqua goes back to Proto-Italic *akʷā- (“water”), and its cognates are Germanic: Gothic 𐌰𐍈𐌰 (aƕa) and Old High German aha, from Proto-Germanic *aχwō (“water”).[4] De Vaan notes that this Germano-Italic word may well be a loanword from a non-Indo-European language.[4]
Earliest recorded meaning
Ovid has the earliest recorded use, in the Metamorphoses:[5][6] there it describes the rain-bringing south wind[7][6] and a lotus growing in water.[2]
Semantic evolution
The adjective meant “of water”, “watery” (Pliny's limus aquaticus, watery mud), and of winds “rainy”.[2][6] Of plants and animals it meant living or growing in or by water, aquatic: Pliny speaks of water birds and of the long necks of aquatic animals.[2][7] Pliny also names a spongy kind of bread panis aquaticus, made light with water.[2] The neuter plural aquātica was used as a noun for marshy places.[6][3]
Christian Latin kept the sense “watery, moist”.[8] Medieval writers used it for anything made of or full of water, and for plants and animals of the water;[9][10] British sources also have it as a noun for a water spaniel.[10] Old French developed popular forms such as ewage,[1] and English aquatic comes from Old French aquatique, the learned form of the same Latin word.[11]
