Hardening or stiffening of the joints due to chronic inflammation or degeneration.
From Greek 'arthron' (joint) + 'skleros' (hard) + '-osis' (condition). A medical term describing how joints become rigid and immobile over time.
This word reveals an ancient medical fear that's still relevant: the idea that our joints could literally turn to stone, losing their flexibility—and interestingly, this inspired doctors to understand why movement and exercise keep joints young.
