'analyticity' originates from 'analytic', which comes from the Greek word 'analytikos', where 'ana-' meant 'up' or 'throughout' and 'lyein' meant 'to loosen'.

'analyticity' was formed in English by adding the suffix '-ity' to 'analytic', and its plural 'analyticities' follows standard English pluralization.

Initially, it meant 'the quality of being analytic', and this meaning has remained consistent in modern usage, especially in mathematics and philosophy.
