'romanization' originates from English, specifically from the word 'Romanize' plus the suffix '-ation', where 'Romanize' meant 'to make Roman or to write in Roman letters'.

'romanization' was formed in English by adding the noun-forming suffix '-ation' to 'Romanize', and eventually became the modern English word 'romanization'.

Initially, it meant 'the act of making something Roman', but over time it evolved into its current meaning of 'representing a language in the Roman alphabet'.
