'justiciability' originates from the Latin word 'justitia,' meaning 'justice,' combined with the suffix '-ability,' indicating a capacity or suitability.

'justitia' transformed into the Old French word 'justise,' and eventually became the modern English word 'justice,' from which 'justiciability' is derived.

Initially, it meant 'the quality of being just,' but over time it evolved into its current meaning of 'suitability for court adjudication.'
