'segmentability' originates from English, specifically formed from the noun 'segment' plus the adjectival suffix '-able' and the nominalizing suffix '-ity', where 'segment' meant 'a part cut off'.

'segment' comes from Latin, specifically the word 'segmentum' (from 'secare' meaning 'to cut'); the components '-able' and '-ity' derive from Latin/French suffixes and were combined in English to form 'segmentability'.

Initially associated with the literal notion of 'a piece cut off,' the compound has evolved to denote the abstract property 'the ability to be divided into segments', especially in technical contexts.
