Sclerotic describes something that has become hard in the medical way — tissue that has sclerosis, or an illness that involves that hardening. Doctors may speak of sclerotic arteries, meaning arteries that have stiffened. Though actually, outside hospitals the word is often used of organisations, rules, or thinking that have gone rigid and hard to change: a sclerotic bureaucracy. That picture comes from the body sense: what should be living and flexible has set hard. There is also an older anatomy use: the sclerotic is the tough white outer coat of the eye (now usually called the sclera). The adjective is the sense meet most. It is not the name of the disease itself; that name is sclerosis.
（組織）硬化的；（制度、思想）僵化的（不是病名本身；病名是 sclerosis／硬化症）
