early 15c., detracten, "disparage, defame, slander," from Latin detractus, past participle of detrahere "to take down, pull down, disparage," from de "down" (see de-) + trahere "to pull" (see tract (n.1)). Literal sense of "take away, withdraw" (c. 1500) is rare in English. Related: Detracted; detracting.
