Word Origin and History for mole
spot on skin, Old English mal "spot, mark, blemish," especially on cloth or linen, from Proto-Germanic *mailan "spot, mark" (cf. Old High German meil, German Mal, Gothic mail "wrinkle"), from PIE root *mai- "to stain, defile" (cf. Greek miainein "to stain, defile," see miasma). Specifically of dark marks on human skin from late 14c.
type of small burrowing mammal (Talpa europea), mid-14c., probably from obsolete moldwarp, literally "earth-thrower." Spy sense first recorded 1974 in John le Carré (but suggested from early 20c.), from notion of "burrowing." Metaphoric use for "one who works in darkness" is from c.1600.
"breakwater," 1540s, from Middle French môle "breakwater" (16c.), ultimately from Latin moles "mass, massive structure, barrier," from PIE root *mo- "to exert oneself" (cf. Greek molos "effort," molis "hardly, scarcely;" German mühen "to tire," müde "weary, tired;" Russian majat' "to fatigue, exhaust," maja "hard work").
unit of molecular quantity, 1902, from German Mol coined 1900 by German chemist Wilhelm Ostwald (1853-1912), short for Molekül (see molecule).
- A small, usually pigmented, benign growth on the skin.
- The amount of an element, compound, or other substance that has the same number of basic particles as 12 grams of Carbon-12. The number of particles making up a mole is Avogadro's number. For elements and compounds, the mass of one mole, in grams, is roughly equal to the atomic or molecular weight of the substance. For example, carbon dioxide, CO2, has a molecular weight of 44; therefore, one mole of it weighs 44 grams.
