'typical' originates from Late Latin, specifically the word 'typicus', where the Greek root 'typos' meant 'impression, pattern'; the suffix '-ness' originates from Old English '-nes(s)e', meaning 'state or quality'.

'typical' changed from Greek 'typikos' to Late Latin 'typicus', then via French 'typique' into English as 'typical'; combining this adjective with the Old English-derived suffix '-ness' produced the noun 'typicalness'.

Initially it meant 'of or relating to a type; characteristic', but over time it evolved into its current meaning of 'the state or quality of being typical; representativeness'.
