Origin: 1250–1300; Middle English < Anglo-French, Old French desparag(i)er to match unequally, equivalent to des-dis-1 + -parag(i)er, derivative of parage equality, equivalent to par(er) to equalize (< Latin parāre;see peer1) + -age-age
early 14c., from O.Fr. desparagier "reduce in rank, degrade," originally "to cause to marry unequally," and thus by extension the disgrace or dishonor involved in this, from des- "away" + parage "rank, lineage" (see peer (n.)). Sense of "belittle" first recorded 1530s. Related:
