Origin of candle
before 900;Middle English,Old Englishcandel < Latincandēla, equivalent to cand(ēre) to shine + -ēla deverbal noun suffix; see candid
Old English candel "lamp, lantern, candle," an early ecclesiastical borrowing from Latin candela "a light, torch, candle made of tallow or wax," from candere "to shine," from PIE root *kand- "to glow, to shine, to shoot out light" (cf. Sanskrit cand- "to give light, shine," candra- "shining, glowing, moon;" Greek kandaros "coal;" Welsh cann "white;" Middle Irish condud "fuel").
Candles were unknown in ancient Greece (where oil lamps sufficed), but common from early times among Romans and Etruscans. Candles on birthday cakes seems to have been originally a German custom. To hold a candle to originally meant "to help in a subordinate capacity," from the notion of an assistant or apprentice holding a candle for light while the master works. To burn the candle at both ends is recorded from 1730.
