First attested in Scottish English (compare Scots stob, stobbe, stabb), from Middle English stabbe ("a stab"), probably a variant of Middle English stob, stub, stubbe, from Old Norse stobbi, stubbi, cognate with Old English stybb. Cognate with Middle Dutch stobbe.
Supposed by some to derive from Scottish Gaelic stob ("to prick, to prod, to push, to thrust"); supposed by others to be from a Scots word.
