Etymology (EN): M.E. mesche “open space in a net,” apparently from O.E. max “net,” earlier mæscre (cf. Dan. maske, Sw. maska, M.Du. maessce, Du. maas “mesh,” O.H.G. masca, Ger. Masche “mesh”).

Etymology (PE): Bâncé “aperture, opening, window” in (Kermânšâhi) Kurd., ultimately from Proto-Ir. *banaka-, from *baH-
“to shine,” cf. Av. bāmya- “light, bright;” Pers. bâm “morning, dawn; splendor, light,” Ossetic bon “day,” probably related to bezel “opening, aperture,” in several dialects of the Fârs province (Lâr, Gerâš, Xonj, Fišvar), → morning.
