torpe
/ˈtoɾpe/ · B1 · adj
clumsy, awkward
From Latin turpis (ugly, shameful), as in English moral turpitude
Latin turpis meant ugly or disgraceful, which is where the dishonest sense comes from. For the clumsy sense, think of the sound-alike torpid: slow and sluggish, as a bungler is. Torpid is only a sound hook, not a related word.
