Word Origin & History

"spot on skin," O.E. mal "spot, mark," especially on cloth or linen, from P.Gmc. *mailan "spot, mark" (cf. O.H.G. meil, Ger. Mal, Goth. mail "wrinkle"), from PIE base *mei-/*mai- "to stain, defile" (cf. Gk. miainein "to stain, defile," see miasma). Of human skin, attested from late 14c.

"burrowing mammal," late 14c., probably from obsolete mouldwarp, lit. "earth-thrower" (common Gmc., cf. O.S. moldwerp, O.H.G. multwurf), from to O.E. molde "earth, soil" (see mold (3)) + weorpan "to throw away" (see warp). Spy sense first recorded
1974 in John le Carré, from notion of "burrowing." Metaphoric use for "one who works in darkness" is from c.1600.
"To much amplifying thinges yt. be but small, makyng mountaines of Molehils." [John Foxe, "Acts and Monuments," 1570]

"breakwater," 1548, from M.Fr. môle "breakwater," from L. moles "mass, massive structure, barrier," from PIE base *mo- "to exert oneself."

unit of molecular quantity, 1902, from Ger. Mol (1900), short for Molekül (see molecule).

mole 1   (mōl)  Pronunciation Key 
A small, usually pigmented, benign growth on the skin.
mole 2   (mōl)  Pronunciation Key 
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.

Mole definition

Heb. tinshameth (Lev. 11:30), probably signifies some species of lizard (rendered in R.V., "chameleon"). In Lev. 11:18, Deut. 14:16, it is rendered, in Authorized Version, "swan" (R.V., "horned owl"). The Heb. holed (Lev. 11:29), rendered "weasel," was probably the mole-rat. The true mole (Talpa Europoea) is not found in Palestine. The mole-rat (Spalax typhlus) "is twice the size of our mole, with no external eyes, and with only faint traces within of the rudimentary organ; no apparent ears, but, like the mole, with great internal organs of hearing; a strong, bare snout, and with large gnawing teeth; its colour a pale slate; its feet short, and provided with strong nails; its tail only rudimentary." In Isa. 2:20, this word is the rendering of two words _haphar peroth_, which are rendered by Gesenius "into the digging of rats", i.e., rats' holes. But these two Hebrew words ought probably to be combined into one (lahporperoth) and translated "to the moles", i.e., the rat-moles. This animal "lives in underground communities, making large subterranean chambers for its young and for storehouses, with many runs connected with them, and is decidedly partial to the loose debris among ruins and stone-heaps, where it can form its chambers with least trouble."

Easton's 1897 Bible Dictionary
