Pronunciation

  • UK: /ˈdɔː.səl/, /ˈdɔː.sl̩/[1]
  • US: /ˈdɔɹ.səl/[1]

Etymology

It is inherited from Middle English dorsal,[2] borrowed from Medieval Latin dorsālis,[3][4][2][5] which stands for Latin dorsuālis (“of the back”),[6][4][7][8] from dorsum (“back”).[3][4][6][9] Barnhart takes it through Middle French dorsal from Late Latin,[10] and Etymonline and Hoad allow Old French dorsal as a source beside the Latin;[6][7] the OED only compares the French word, recorded from the 13th–14th century.[3] The Latin noun dorsum is of uncertain origin.[6][10]

Earliest recorded meaning

Back, rear; of a cutting instrument, having a back, that is, only one cutting edge: probably before 1425, in a Middle English translation of Guy de Chauliac's Grande Chirurgie.[2][10] The OED's first record of the knife sense is in Robert Copland's Questyonary of Cyrurgyens (probably 1541).[3]

Semantic evolution

The word began as a surgeons' term, and the sense "having one edge" was obsolete by the mid 16th century.[9][3] The anatomical sense, "of or on the back of an animal", is first recorded in Chambers's Cyclopaedia,[10][3] dated 1727 by Barnhart and Merriam-Webster and 1728 by the OED.[10][11][3] From the early 19th century it was applied in zoology and botany to the back or outer surface of any organ,[3] usually in contrast with ventral.[3][12] In 1933 Leonard Bloomfield used it in phonetics for sounds made with the back of the tongue.[3] As a noun it became short for a dorsal fin or a dorsal vertebra (1831),[3] and in church use a variant of dossal, a hanging behind an altar (1870).[3][13]
