'anglicize' originates from Late Latin 'Anglicus' (meaning 'English') combined with the suffix '-ize' (from Greek '-izein' via Latin/French), forming a verb meaning 'to make English'.

'anglicize' developed from Latin 'Anglicus' and influenced by French forms such as 'angliciser' (or 'angliciser'/'angliciser'), and entered English as 'anglicize' with the productive English suffix '-ize'. The adjective/past participle form 'anglicized' followed regular English verb inflection.

Initially it meant 'to render or make English' (in language, style, or character); over time the meaning has remained broadly the same but has extended from formal Latin-derived uses to ordinary English usage (including names, words, customs).
