'aroynting' originates from Early Modern English dialect, specifically the verb 'aroint'/'aroynt', where the prefix 'a-' functioned as an intensifier and the root 'roint'/'oint' is of uncertain origin (possibly related in sense to verbs meaning 'to rout' or 'to drive off').

'aroynt' appears in Middle and Early Modern English dialectal forms such as 'aroint' and 'aroynt' and was used as an imperative or verb meaning 'be gone' or 'drive away'; it survived chiefly in literary and regional texts before becoming obsolete in standard modern English.

Initially it meant 'be gone' or 'begone' (an order to depart); over time it remained largely unchanged in sense but fell out of common use and became archaic, now encountered mainly in quotations or dialect records.
