词源
The verb is derived from Late Middle English calcinen (“(alchemy, medicine) to heat (something) until it turns to powder; to change the nature of (something) by heating”) [and other forms], from Old French calciner (modern French calciner (“to calcinate; to calcine”)) and from its etymon Medieval Latin calcināre (“(alchemy) to burn like lime; to reduce to calx”), from Late Latin calcīna (“inorganic material containing calcium, lime”) + -āre (suffix forming present active infinitive forms of verbs). Calcīna is derived from Latin calcis, the genitive singular of calx (“chalk; limestone”), possibly from Ancient Greek χᾰ́λῐξ (khắlĭx, “small stone, pebble; gravel, rubble”); further etymology unknown, possibly Pre-Greek. The noun is derived from the verb.
