History
Etymology
From Middle English deforme (“out of shape, deformed”) [and other forms], from Middle French deforme (modern French difforme (“misshapen, deformed”)), or directly from its etymon Latin dēfōrmis (“departing physically from the correct shape, deformed, malformed, misshapen, ugly; (figuratively) departing morally from the correct quality, base, disgraceful, shameful, unbecoming”), from dē- (prefix meaning ‘away from; from’) + fōrma (“form, appearance, figure, shape; fine form, beauty; design, outline, plan; model, pattern; mould, stamp; (figuratively) kind, manner, sort”) (further etymology unknown; perhaps related to Ancient Greek μορφή (morphḗ, “form, shape; appearance; outline; kind, type”), probably from Pre-Greek, but there is no consensus) + -is (suffix forming adjectives of the third declension).
From Middle English deformen (“to disfigure, distort, or mar; (figuratively) to disfigure morally; to defame; to dishonour”) [and other forms], equivalent to de- + form, from Old French deformer [and other forms] (modern French déformer (“to contort, distort, twist out of shape; (figuratively) to pervert”)), or directly from its etymon Latin dēfōrmāre (whence Medieval Latin difformāre), the present active infinitive of dēfōrmō (“to fashion, form; to delineate, describe; to design; to deform, disfigure; to mar, spoil”), from dē- (prefix meaning ‘away from; from’) + fōrmō (“to fashion, form, shape; to format”) (from fōrma (noun); see further at etymology 1). Cognates * Catalan deformar (“to deform”) * Italian deformare (“to deform; to distort, warp”) * Occitan deformar * Portuguese deformar (“to deform”) * Spanish deformar, desformar (“to deform, disfigure”)
