Etymology From Middle English flashe, flaske, also found as flosche and flushe (whence modern English flosh and flush), used in Middle and modern English for bodies of water with varying emphasis on them being "pools" or "marshes". It is not entirely clear whether these constitute a single term with varied spellings, or have distinct etymologies. The form flash, flashe is often suggested to be from Old French flache, French flaque, which is of Germanic origin, akin to Middle Dutch vlacke (“an estuary, flats with stagnant pools”). See flush for more on that form.
