mizzy

From Middle English misy (“swamp, bog”), of uncertain origin. Possibly from Old English *mȳsiġ, *mīesiġ, from Proto-West Germanic *miusiju, from Proto-Germanic *miusijō (“swamp, bog”, literally “mossy place”), from Proto-Germanic *meusą (“moss, moor”), related to Old Norse mýrr ("swamp, bog, moor"; whence English mire), Middle English mes, mease, mise, mese (“moss”), from Old English mēos (“moss”). Compare also dialectal English mizzick, mizzack, mezzack, mizuk, perhaps the same word with a suffix akin to -ock.
