'advena' originates from Latin, specifically the word 'advenire,' where 'ad-' meant 'to' and 'venire' meant 'come.'

'advenire' transformed into the Latin word 'advena,' and eventually became the modern English word 'advenae' through historical usage in Roman contexts.

Initially, it meant 'one who comes to,' but over time it evolved into its current meaning of 'foreigner or newcomer.'
