'justiciable' originates from French, specifically the word 'justiciable', where 'justici-' meant 'justice' and '-able' meant 'capable of'.

'justiciable' changed from the French word 'justiciable' and eventually became the modern English word 'justiciable'.

Initially, it meant 'capable of being judged', but over time it evolved into its current meaning of 'capable of being decided by a court of law'.
