'aroynts' originates from Early Modern English, specifically recorded as 'aroynt' or 'aroint', where the exact root is uncertain but the form appears in 16th–17th century English as a command meaning 'be gone'.

'aroynt' appears in Middle/Early Modern English spellings such as 'aroynte' and 'aroint' and was used as an imperative/exclamation; over time the word fell out of regular use and is now considered archaic or dialectal.

Initially it meant 'be gone' or 'away' as a forceful command; that core meaning has remained, but the term became obsolete and rare in later English.
