What does sclerose mean?
Sclerose is a verb meaning to become hard, rigid, or fixed, most often used for the progressive hardening or scarring of tissue. In medical contexts, it describes a process rather than a named condition: a valve or other structure may sclerose over time as disease develops. The verb can also be used figuratively for situations that become entrenched or resistant to change, as when a dispute “scleroses” into permanent hostility. Its language is primarily medical, while the figurative sense is comparatively uncommon and formal. The word is related etymologically to sclerosis and sclerotic, both of which share the Greek root sklēros, meaning “hard.” Knowing sclerose therefore helps distinguish the process of hardening from the condition or condition-related state described by sclerosis.
