'aroynt' originates from Early Modern English, specifically the word 'aroint', where 'a-' is an old prefix used in many imperatives/commands and the remainder is of uncertain origin.

'aroynt' changed from the Middle English/Early Modern English form 'aroint' and was used in Early Modern English drama and texts before falling into obsolescence in later modern English.

Initially, it meant 'begone' or 'be gone' as a forceful command; over time the word's meaning stayed similar but the term became archaic and is no longer in common use.
