词汇	micron
词源	micron n. "one millionth of a meter," by 1883, coined in French from Greek mikron, neuter of mikros "small" (see micro-) and formally adopted Oct. 2, 1879, by the Comité International des Poids et Mesures. It was replaced 1968 by the micrometre. Entries linking to micron micro- word-forming element meaning "small in size or extent, microscopic; magnifying;" in science indicating a unit one millionth of the unit it is prefixed to; from Latinized form of mikros, Attic form of Greek smikros "small, little, petty, trivial, slight," perhaps from PIE smika, from root smik- "small" (source also of Old High German smahi "littleness"), but Beekes thinks it a Pre-Greek word. updated on January 10, 2019
