Etymology

From Middle English mesche, from Old English masc (“net”) (perhaps influenced in form by related Old English mæscre (“mesh, spot”)) both from Proto-Germanic *maskrǭ, *maskwǭ, from Proto-Indo-European *mezg- (“to knit, twist, plait”). Akin to Old High German māsca (“mesh”), Old Saxon maska (“net”), Old Norse mǫskvi, mǫskun (“mesh”).
