'anchylose' originates from French, specifically the word 'anchylose', which comes from Greek 'ankylos', meaning 'bent' or 'crooked'.

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

Initially, it meant 'to make stiff or crooked', but over time it evolved into its current medical meaning of 'to cause a joint to become stiff or immobile'.
