Etymology
It is inherited from Middle English mersh, inherited from Old English mersc (“marsh, swamp”) (also merisc),[2][3][4] from Proto-Germanic *mariskō,[2][3] cognate with Old Frisian mersk, Old Saxon mersk, Middle Dutch mersch and German Marsch;[2][3][4] probably from *mari- (“sea”), from Proto-Indo-European *mori- (“body of water”) (see mere).[3][5] The Old English word may have been influenced by Late Latin mariscus (“marsh”),[6] which itself came from the West Germanic word and gave Old French mareis, whence the old English form marish.[4]
Earliest recorded meaning
A tract of low wet land, flooded in winter: about 725 in the OED, about 700 in Barnhart.[7][2] Middle English mersh is from about 1250, in The Owl and the Nightingale.[2]
Semantic evolution
The change of vowel from e to a began in the 15th century and is usual for er before a consonant, as in darling, far and hart;[3] marsh is recorded probably about 1450.[2] Locally, a meadow or stretch of grassland near a river or the sea is called a marsh, from 1787.[7] Marsh gas, methane from decaying matter, is attested by 1819.[3]
