Pronunciation
- IPA: /mjuːl/, /mjuːəl/[1]
Etymology
It is inherited from Middle English mule, partly inherited from Old English mūl and partly borrowed from Old French mul,[2][3][4][5][6] both from Latin mūlus (“mule”),[2][3][4][5][6] probably, like Greek múklos “pack ass”, a loanword from a language of Asia Minor.[4] The unrelated mule “slipper” is borrowed from Middle French mule,[2][3][4][5] from Latin mulleus (“red shoe worn by Roman magistrates”).[2][3][4][5]
Earliest recorded meaning
The offspring of a male donkey and a mare (c. 1000).[7][3]
Semantic evolution
Though the mule is proverbial for obstinacy, the OED finds no good grounds for this.[4] The word was applied to a stupid or obstinate person from about 1470,[7][4] the sense “stubborn” being established by the 18th century.[4] It was used of hybrids in general,[7][5] and of Samuel Crompton's spinning machine (mule-jenny, 1788), a “hybrid” of the machines of Arkwright and Hargreaves.[4] In 20th-century slang a mule is a person who smuggles drugs (1935).[7][5][6] The slipper mule dates from 1562.[7][3][5]
