'Englishify' is a modern formation combining the noun 'English' and the verb-forming suffix '-ify' (from Latin-derived '-ificare'), meaning 'to make or render'.

'-ify' comes from Latin '-ificare' via Old French and Late Latin, where '-ficare'/'-fic-' conveyed 'make' or 'do'; combining it with 'English' produced the neologism 'Englishify'.

Initially the suffix '-ify' meant 'to make' (in a general sense); combined with 'English' it now specifically means 'to make English' (either linguistically or culturally).
