Sclerotic

Sclerotic is an adjective that means rigid or unresponsive. Our word of the day comes from the Greek word skleros (SLARE ose) which means ‘hard.’ You could think of the state of being sclerotic similar to something being hard or rigid. Here’s an example of sclerotic in use: After running the marathon, my legs felt sclerotic for weeks. Running or even walking was a difficult task.
