quinteau

Etymology
Emigrants from Perche brought the term to New France, and hence into Canadian and Louisiana French. Its pronunciation was "normalized" (to drop the [i̯], to match the pronunciation of other words ending in -eau) either by the Perche speakers when they spoke to non-Perche speakers, or by those other speakers after they borrowed the term.

Noun

 * 1)  a heap, pile, or stack, such as of sugar or hay
