Etymology and origin of the English word cod

Confidence
Unknown
First attested
1357

Pronunciation

  • IPA: /kɒd/ (UK); /kɑd/ (US)[1]

Etymology

Its origin is unknown.[2][3][4] Barnhart suggests a link with the older noun cod, a bag or seed pod (from Old English codd), through codnet, probably a bag-shaped fishing net (1299),[5] and Hoad likewise wonders whether it meant a bag fish, from its appearance;[3] Etymonline finds no conclusive connection with the Germanic word for bag.[2]

Earliest recorded meaning

The sea fish Gadus morhua: 1357 in the OED and Barnhart,[6][5] the mid-14th century in Etymonline.[2] It occurs earlier in a surname, Thomas cotfich, in the late 13th century (cotfish, 1273).[2][5]

Semantic evolution

Codfish is from the 1560s.[2] Cod-liver oil was known by the 1610s, recommended as a medicine from 1783, but became a popular remedy only after 1825.[2] Cod's head was 16th-century slang for a blockhead.[3]
