Etymology

1. 1410, from L. deducere "lead down, derive" (in M.L. "infer logically"), from de- "down" + ducere "to lead" (see duke). Originally literal, sense of "draw a conclusion from something already known" is first recorded 1529, from M.L.
2. From Late Middle English deducen (“to demonstrate, prove, show; to argue, infer; to bring, lead; to turn (something) to a use; to deduct”), borrowed from Latin dēdūcere, the present active infinitive of dēdūcō (“to lead or bring out or away; to accompany, conduct, escort; (figuratively) to derive, discover, deduce”); from dē- (prefix meaning ‘from, away from’) + dūcere (the present active infinitive of dūcō (“to conduct, guide, lead; to draw, pull; to consider, regard, think”), ultimately from Proto-Indo-European *dewk- (“to lead; to draw, pull”)).
