non-cancerous

The word is a modern medical English formation built from classical components. The core noun "cancer" originates from Latin, where it literally meant "crab," a comparison likely inspired by the invasive, grasping appearance of some tumors. The suffix "-ous," of Latin origin via French, is a prolific adjective-forming element. The prefix "non-," directly from Latin, is a straightforward negator. Therefore, the literal morphemic construction "not having the qualities of a cancer" logically yields the modern medical term for a benign growth, providing a clear, descriptive antonym to "cancerous."

Structure: non (not) + cancer (cancer) + ous (adjective suffix) - non: Latin origin, a prefix meaning "not." - cancer: Latin origin, meaning "crab" and later "malignant tumor," serving as the core noun. - ous: Latin suffix via Old French, forming adjectives meaning "full of" or "having the qualities of."
