/prɪˌsɪpɪtəˈbɪlɪti/ noun

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).
