'conventionally-united' originates from the combination of 'conventionally' and 'united', where 'conventionally' is derived from 'convention', meaning 'a way in which something is usually done', and 'united' from 'unite', meaning 'to come together'.

'conventionally' changed from the Latin word 'conventio' meaning 'assembly' and 'united' from the Latin 'unitus', eventually forming the modern English term 'conventionally-united'.

Initially, it meant 'joined together by common agreement', but over time it evolved into its current meaning of 'formed or brought together in a manner that adheres to established norms'.
