preach: [13] Preach goes back ultimately to Latin praedicāre ‘proclaim’ (source also of English predicament and predicate). Its Old French descendant was prechier, whence English preach (English had actually acquired the word before, directly from Latin in the Anglo-Saxon period, as predician ‘preach’, but this had died out before the Old French word arrived). The semantic shift in the Latin verb from ‘proclaiming’ to ‘preaching’ took place in the early Christian period.
