'noticeability' originates from the word 'noticeable', which comes from the Latin word 'notitia', meaning 'a being known'.

'notitia' transformed into the Old French word 'notice', and eventually became the modern English word 'noticeable', leading to 'noticeability'.

Initially, it meant 'a being known', but over time it evolved into its current meaning of 'the quality of being easy to see or recognize'.
