Through Middle English from the Old French noun oracle (temple, place of prayer, divine pronouncement) and the Latin neuter noun orac(u)lum, orac(u)li (prophecy, divine announcement, place where oracles are given). The Latin noun is a combination of the Latin verb oro, orare, oravi, oratum (speak, argue, pray, beg, beseech) and the Latin diminutive adjectival suffix -culus, -cula, -culum. The verb was formed from the Latin neuter noun os, oris (mouth).
