'extractability' originates from Modern English, specifically built from the verb 'extract' plus the adjective-forming suffix '-able' and the noun-forming suffix '-ity', where 'extract' ultimately comes from Latin 'extrahere' (from 'ex-' meaning 'out' and 'trahere' meaning 'to draw').

'extractability' changed from the Modern English adjective-based form 'extractable' combined with the suffix '-ity' to form the abstract noun 'extractability'. The verb 'extract' itself derives from Latin 'extrahere' and passed into Old French/Middle English forms before stabilizing in Modern English.

Initially the root idea meant 'to draw out' (referring to physical drawing or pulling out). Over time this developed into the abstract noun sense 'the ability or degree to be extracted', used for materials, data, information, etc.
