"to wish or long for, express a wish to obtain," c. 1200, desiren, from Old French desirrer (12c.) "wish, desire, long for," from Latin desiderare "long for, wish for; demand, expect," the original sense perhaps being "await what the stars will bring," from the phrase de sidere "from the stars," from sidus (genitive sideris) "heavenly body, star, constellation" (but see consider). Related: Desired; desiring.
