Emily Dickinson Lexicon

JEER, v.i. [G. scheren, to rail at, to jeer, to shear, to shave; D. scheeren, Dan. skierer, Sw. skära, Gr. κειρω, without a prefix. These all seem to be of one family, Class Gr. The primary sense is probably to rub, or to cut by rubbing; and we use rub in a like sense; a dry rub, is a keen, cutting, sarcastic remark.]

To utter severe, sarcastic reflections; to scoff; to deride; to flout; to make a mock of; as, to jeer at one in sport. – Herbert.
