noun

  1. 1

    A naevus, a pigmented, slightly raised, and sometimes hairy spot on the skin.

Etymology

From Middle English mole, mool, from Old English māl (“a mole, spot, mark, blemish”), from Proto-West Germanic *mail, from Proto-Germanic *mailą (“spot, wrinkle”), from Proto-Indo-European *mel-, *melw- (“dark, dirty”), from Proto-Indo-European *mey-, *my- (“to soil, sully”). Cognate with Scots mail (“spot, stain”), Saterland Frisian Moal (“scar”), German dialectal Meil (“spot, stain, blemish”), Gothic 𐌼𐌰𐌹𐌻 (mail, “spot, blemish”).

Etymology

From Middle English molle, molde, mole (“mole”), ultimately from Proto-West Germanic *mol(h), from Proto-Germanic *mulaz, *mulhaz (“mole, salamander”), from Proto-Indo-European *molg-, *molk- (“slug, salamander”), from Proto-Indo-European *(s)melw- (“to grind, crush, beat”). Cognate with North Frisian mull (“mole”), Saterland Frisian Molle (“mole”), Dutch mol (“mole”), German Low German Mol, Mul, Mull (“mole”), German Molch (“salamander, newt”), Old Russian смолжь (smolžʹ, “snail”), Czech mlž (“clam”). Derivation as an abbreviation of Middle English molewarpe, a variation of moldewarpe, moldwerp (“mole”) in Middle English is unexplained and probably unlikely due to the simultaneous occurrence of both words. See mouldwarp.

verb

noun

  1. 1

    slangA moll, a bitch, a slut.

Etymology

From moll (from Moll, an archaic nickname for Mary), influenced by the spelling of the word mole (“an internal spy”), and due to /mɒl/ and /məʊl/ merging as [ˈmɔʊɫ] in the Australian accent.

noun

  1. 1

    A massive structure, usually of stone, used as a pier, breakwater or junction between places separated by water.

    Its extreme downtown is the battery, where that noble mole is washed by waves, and cooled by breezes, which a few hours previous were out of sight of land.

    Using the countless tons of rock from the cliff-face, supplemented by much more from inland, they threw out a huge breakwater, 2,000 ft. long and 80 ft. high, roughly at right angles to the quay, so forming an almost completely sheltered corner. Fifty years later, this massive mole is still standing up to the worst that the Irish Sea can do.

    [about Saint-Tropez] Yachts and fishing boats fill the little square of water, which is surrounded on two sides by quays, on the third by a small ship-repairing yard and on the fourth by the mole where the fishing boats moor and the nets are spread out to dry.

  2. 2

    rareA haven or harbour, protected with such a breakwater.

  3. 3

    historicalAn Ancient Roman mausoleum.

Etymology
