late 14c., huske "dry, outer skin of certain fruits and seeds," of unknown origin. "A common word since c 1400 of which no earlier trace has been found" [OED]. Perhaps from Middle Dutch huuskyn "little house, core of fruit, case," diminutive of huus "house," or from an equivalent formation in English (see house (n.)).
"strip off the husks of," 1560s, from husk (n.). Related: Husked; husking.
