bayou

English bayou, recorded by 1763, came from Louisiana French bayouque. An early Choctaw *bayok is a plausible proposed source, but the historical form and its alleged contraction to modern bók are not securely attested.

“Bayou is not simply a French invention—but “it definitely comes from Choctaw bayuk” is too certain. The Choctaw route is plausible, important, and still evidentially insecure.”

Crossing into a starred form changes the evidence class. The interface marks that crossing, preserves confidence, and never manufactures the next root to make the picture look complete.
