Forms

bayou m (plural bayous)[1] Older spellings bayouk (1699), baijou (1740) and bayouc.[2][3][4]

Etymology

It is borrowed from Choctaw bayuk (“small river, creek”).[2][1][3][4] The TLFi dates the adaptation to the second half of the 17th century, when the French first explored Louisiana.[2] Rey describes it as a word of the French of the Cajuns of Louisiana.[4]

Earliest recorded meaning

It is first recorded in 1699 as bayouk, for a stretch of still water that the native people called by that name, “shallow or stagnant water, a side channel of a river” in Louisiana.[2][5]

Semantic evolution

The form baijou is found in 1740 with the sense “small river”, and bayou in 1758, when Le Page de Pratz described it as a large stream of dead water with little or no current.[2] The word then passed into geography with a wider sense (1869),[4] and was also applied to river channels in Africa.[6] American English took bayou from Louisiana French in 1766.[7]

Timeline

  • 1699 – Bayouk is recorded in Louisiana.[2][3][4]
  • 1740 – Baijou “small river” appears in a journal of the Mississippi war.[2]
  • 1758 – Bayou is used by Le Page de Pratz in his history of Louisiana.[2][6]
  • 1766 – English bayou is first recorded.[7]
  • 1869 – The word is used in geography outside Louisiana, of Africa.[4][6]

Meanings

Noun

  1. In Louisiana and the lower Mississippi, a body of shallow, slow-moving or stagnant water: a side channel of a river or a lake left in an abandoned meander.[2][8][9]
  2. (Louisiana) A stream, a small river.[1]

Usage notes

In the French of New Caledonia a separate feminine noun bayou, from Indonesian bayu “elder sister”, a form of address, means a cleaning woman, and also an Indonesian woman; it is familiar and dated.[4][10]
