Root Breakdown
Root-derivedBuilt on Latin praecipitare 'to throw head-first' (prae- head-foremost + caput head). Precipitation is what is thrown headlong: water hurled out of the sky (rain, snow) or a solid thrown down out of a solution (a chemical precipitate). The 'sudden, headlong' sense gives the third meaning, reckless haste.
