'Englishman' originates from Old English, specifically from elements 'Englisc' (meaning 'of the Angles/English') and 'mann' (meaning 'person' or 'man').

'Englishman' changed from Old English 'Engliscmann' (and Middle English forms like 'Englishman'/'Englisshman') and eventually became the modern English word 'Englishman'.

Initially it referred to a person of the Angles (a Germanic tribe) or broadly a person from the English people; over time it evolved into its current meaning of 'a man from England or of English nationality.'
