From Middle English herse, hers, herce, from Old French herce, from Medieval Latin hercia, from Latin herpicem, hirpex; ultimately from Oscan 𐌇𐌉𐌓𐌐𐌖𐌔 (hirpus, “wolf”), a reference to the teeth, ultimately from Proto-Indo-European *ǵʰers- (“stiff, rigid, bristled”). The Oscan term is related to Latin hīrsūtus (“bristly, shaggy”), whence English hirsute. Doublet of herse (“kind of gate”).
