'arability' originates from Modern English, specifically formed from the adjective 'arable' + the nominalizing suffix '-ity' (from Latin '-itas'), where the Latin verb 'arare' meant 'to plough'.

'arability' developed when the Middle English/Old French adjective 'arable' (from Latin 'arabilis') was combined with the suffix '-ity' in Modern English to form a noun meaning 'the state or condition of being arable'.

Initially related to the adjective meaning 'fit to be ploughed' (from Latin 'arabilis'), it evolved into the noun meaning 'the quality or condition of being suitable for cultivation'.
