Pronunciation
- IPA: /ˈsɝlɔɪn/ (US)[1]
Etymology
It comes from Middle English surloine, surloyne,[2][3][4] from Middle French surlonge (“upper part of the loin”),[2][3][4][5][6] from Old French sur (“over, above”) + loigne (“loin”).[2][3][4][5] The French preposition comes from Latin super.[2][5] The spelling with sir- appeared in the 17th century[3][4] and may have been influenced by sir.[4]
Earliest recorded meaning
A cut of beef (before 1425 in Barnhart, as surloyne);[3][4] the OED's first quotation, for the upper and better part of the loin, is from 1554.[7][5]
Semantic evolution
A story that an English king knighted the cut for its excellence dates to Fuller's Church-History of Britain (1655),[4] but Etymonline finds no evidence for it;[4] the tale was told variously of Henry VIII, James I and Charles II.[4] Puns on Sir Loin are recorded from 1630.[7]
