Origin

Early 16th century: from Latin praecipitat- thrown headlong, from the verb praecipitare, from praeceps, praecip(it)- headlong, from prae before + caput head. The original sense of the verb was ‘hurl down, send violently’; hence ‘cause to move rapidly’, which gave rise to sense 1 (early 17th century).
