mid-14c., from Old French detraccion "detraction, disparagement, denigration," from Latin detractionem (nominative detractio) "a drawing off," from past participle stem of detrahere "take down, pull down, disparage," from de- "down" (see de-) + trahere "to pull" (see tract (n.1)). The fem. form detractress is attested from 1716.
