mussel

Etymology

It is inherited from Middle English muscle, also moscle and muskel,^[2][3] inherited from Old English muscle, also muscelle, musle and muxle,^[4][5][6][7] borrowed from Medieval Latin muscula (“mussel”),^[8][9] recorded from the 8th century in British sources.^[8] Barnhart, Klein and Merriam-Webster reconstruct the source as Vulgar Latin *muscula, Merriam-Webster with a prehistoric West Germanic word in between.^[3][10][5] It is an altered form of Latin mūsculus (“little mouse; muscle; mussel”), the diminutive of mūs (“mouse”), the source also of muscle.^[4][11][5] The OED sees later reinforcement from Anglo-Norman moskle, also muscle and muxle.^[8] The modern form owes its double s to Middle Low German mussel and Middle Dutch mosscele, according to Hoad, the Shorter Oxford, the Oxford Dictionary of English and Ayto,^{[7][6][12][11]} or perhaps to Dutch mossel, according to the American Heritage Dictionary.^[9] The same source gave Old Saxon muskula, Old High German muscula, German Muschel, Old French moulle and French moule.^[8][4]

Earliest recorded meaning

The shellfish, from the first: Barnhart records the form musscel before 850,^[3] and the OED's first record is the early Old English Cleopatra Glossary.^[8] The place name Musselburgh, in Midlothian, appears as Muselburg in 1070.^[8]

Semantic evolution

The Latin name came from a likeness to a mouse, in size and shape according to Etymonline, in shape and colour according to Ayto.^[4][11] Merriam-Webster's Book of Word Histories thinks it uncertain whether the comparison was directly to a mouse or to a muscle, since the animal looks like little more than a muscle in a shell, and points out that Ancient Greek μῦς (mûs) also meant both "mouse" and "mussel".^[13][14] In Middle English muscle also named a kind of siege engine.^[2] The two meanings of muscle were long written alike: the spelling mussel appears about 1600, in Shakespeare's The Tempest (1610) according to Barnhart, and was not fully established until the 1870s.^[4][3] Dialects in Scotland, Ireland and England had many compounds, such as mussel-brose, broth made from mussels, and mussel-scaup, a mussel bed.^[15] A mussel was also a kind of plum in 1718,^[8] and the verb, in the passive, meant to be poisoned by eating mussels, from 1852.^[8]
