'measurability' originates from English, specifically formed from the adjective 'measurable' combined with the nominal suffix '-ity'; 'measure' ultimately comes from Old French 'mesure', from Latin 'mensura' (from 'metiri' meaning 'to measure'), while the suffixes '-able'/'-ability' indicate 'capable of' and '-ity' indicates 'state or condition'.

'measure' changed from Old French 'mesure' (from Latin 'mensura') into Middle English 'measure'; the adjective 'measurable' developed by adding the suffix '-able' to 'measure', and 'measurability' was later formed by adding '-ity' to 'measurable'.

Initially related to the action or process of measuring ('measure' as an act), the term evolved (via 'measurable' and suffixation) to denote the property or degree of being capable of measurement ('measurability').
