Etymology: Ancient Greek speakers used "skleros" to describe things that were hard to the touch or hard to bend, such as dried wood, stone, or a stubborn person. The same root produced a family of medical terms in modern English. The white outer coat of the eye is the "sclera," named for its toughness compared with the softer tissues inside it. "Sclerosis" combines the root with the suffix "-osis," meaning an abnormal condition, so it describes tissue that has become hardened or scarred. The root's meaning stayed close to physical firmness, and its metaphorical use grew from that. A rigid structure and an unyielding attitude both draw on the same idea of resisting pressure. Because the root also appears in modern scientific coinages, readers often meet it first in anatomy and medicine rather than in everyday Greek.
