'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 a term used in English to describe a foreigner or newcomer.

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