Morphology
identifiability = identifiable (transparent) = identify + able + ity
The noun is formed by adding the noun-forming suffix '-ity' to the adjective 'identifiable', which itself is transparently formed from 'identify' + '-able'.
Etymology
The word identifiability comes from identify and identity, which trace back to Latin parts meaning 'same' (idem) and 'make' (facere), with -able meaning 'able to' and -ity meaning 'a quality'. So in statistics identifiability is the quality that lets you find each model parameter exactly from the data and not confuse them.
