cack-handed

First recorded in 1850–55; origin uncertain; perhaps from Old Norse keikr “bent backwards”; akin to Danish keite “left-handed”; perhaps from English dialect cack, keck “awkward” (of unknown origin). An obsolete noun sense “excrement” is found in Old English (in cac-hūs “latrine” ); the obsolete verb sense ( mid-15th century ) appears in Middle English cakken “to void excrement,” from Latin cacāre; akin to Greek kakkân “to void excrement,” Middle Irish cacc “dung,” and perhaps to Greek kakós “bad”
