Etymology: "Precipitations" is simply the plural of "precipitation," the noun for the falling of water from the sky in any form. The underlying idea is older than the weather sense: the Latin "praecipitare" meant to throw or hurl headlong, from "prae" (forward, before) and "caput" (head), so to fall head first. Latin "praecipitatio" carried that sense of a headlong plunge, and the word passed into Middle French as "précipitation" before reaching English. The meaning moved from motion to matter through chemistry and weather. A substance that suddenly falls out of a solution as a solid is "precipitated," and by the same logic rain, snow and hail, falling from clouds, came to be called precipitation. The plural form is used mainly in technical contexts, such as climate records, where totals from different periods or places are compared.
