Pronunciation

  • Classical: [aˈkʷaː.ti.oː][1]
  • Ecclesiastical: [aˈkʷat.t͡si.o][1]

Forms

aquātiō f (genitive aquātiōnis); third declension[1]

Etymology

It is from Latin aquor (“to fetch water”) + -tiō.[2][3][4] The verb is made from aqua (“water”),[3] which goes back to Proto-Italic *akwā- (“water”).[5] Cognate with Old High German aha, from Proto-Germanic *aχwō (“water”);[5] de Vaan adds that the shared word may have been borrowed from a non-Indo-European language.[5]

Earliest recorded meaning

Cicero is the first to use it, in On Duties, of the place where the people of Syracuse draw their water: hīc aquātiō.[2][3][6]

Semantic evolution

It was a military word for fetching water: Caesar has troops advancing to get water, the Bellum Africum a long and narrow water supply, and Livy water within a spear's throw.[2][3] Vegetius names it with gathering wood and forage among the tasks to be kept safe from the enemy.[3] Columella uses the plural for watering places for livestock, and Pliny the Elder for the stations on a route laid out by the water supply.[2][7] Palladius uses it for the watering of plants,[4][7] and Pliny for autumn rains, or pools left by rain, in which frogs are born.[2][7]

Medieval charters use it for a watering place and for washing,[8] and an English account of 1365 for the watering of cattle.[9] Its descendants include Italian acquazzone (“downpour”) and Romansh auazun.[1][10]
