'non-' originates from Latin, specifically the word 'non', where 'non' meant 'not'. 'Angolan' originates from Portuguese, specifically the place name 'Angola', which itself comes from the Kimbundu title 'Ngola'.

'Angola' was adopted into Portuguese from the Kimbundu title 'Ngola'; the English demonym 'Angolan' developed from the place name 'Angola'; adding the English prefix 'non-' produced 'non-Angolan', and its plural form is 'non-Angolans'.

Initially, 'Ngola' referred to a local title (a leader); over time it came to name the region 'Angola' and its people; 'Angolan' came to mean 'a person from Angola', and 'non-Angolan' now means 'a person who is not from Angola'.
