Origin of precipitation¹

First recorded in 1425–75; late Middle English, from Latin praecipitātiōn-, stem of praecipitātiō “a casting down headlong,” equivalent to praecipitāt(us) “cast down headlong” (past participle of praecipitāre precipitate ) + -iō -ion

Example Sentences

From BBC

From Los Angeles Times

While the air will be cold enough for precipitation to fall as sleet or snow for some parts of the UK, where and how much may fall will only really be known over the coming days.

From BBC
