Vlaie

In the Hudson Valley of eastern United States, a vlaie, vly /vlaɪ/ or fly /flaɪ/ is a swamp or marsh. It also applies to creeks and areas in the vicinities. The term appears in place names in areas of Dutch influence, formerly New Netherland.

The terms are from a dialectal form of the Middle Dutch word valeye ("valley", spelled vallei in Modern Dutch). However, the meaning shifted to "swamp" when used by New Netherlanders. Variants such as vley and vlei are also found. The English spelling of vleigh is probably under influence of rhymes like sleigh and weigh.

The Afrikaans word vlei ("shallow lake") is a cognate, descended from the same Middle Dutch word. The Vlie, a channel in Frisia, may not be related, as it is likely from the Latin Flevo.
