'analysability' originates from English, specifically from the word 'analyse' with the suffix '-ability', where 'analyse' meant 'to examine in detail' and '-ability' meant 'the quality of being able to'.

'analyse' (from French 'analyser', from Medieval Latin 'analysare', from Greek 'analusis') combined with '-ability' to form 'analysability' in modern English.

Initially, it meant 'the quality of being able to be analysed', and this meaning has remained consistent in modern usage.
