Origin and history of imbue

late 14c., from Old French imbiber, embiber "to soak into," and directly from Latin imbibere "absorb, drink in, inhale," from assimilated form of in- "into, in, on, upon" (from PIE root *en "in") + bibere "to drink," related to potare "to drink," from PIE root *po(i)- "to drink." Figurative sense of "mentally drink in" (knowledge, ideas, etc.) was the main one in classical Latin, first attested in English 1550s. Related: Imbibed; imbibing.

"an overlapping of edges" (as of roof tiles, etc.), 1640s, from French imbrication, noun of action from stem of Latin imbricare "to cover with tiles," from imbricem (nominative imbrex) "curved roof tile used to draw off rain," from imber (genitive imbris) "rain, heavy rain; rainwater," from PIE *ombh-ro- "rain" (source also of Sanskrit abhra "cloud, thunder-cloud, rainy weather," Greek ombros "rain, a shower"), from root *nebh- "moist; water" (see nebula).
