What does degenerative mean?
"Degenerative" is an adjective describing something that worsens progressively over time, most commonly used in medical contexts to characterize diseases and conditions involving gradual deterioration of the body's tissues, organs, or nervous system — as in degenerative arthritis, degenerative disc disease, and degenerative neurological disorders such as Alzheimer's and Parkinson's. In these uses it signals that a condition advances slowly and, typically, irreversibly, distinguishing it from acute illnesses that strike suddenly. The word derives from the Latin "degenerare," meaning to decline from one's original quality or nature, and it retains a broader figurative sense of steady decay or decline when applied outside medicine, as in descriptions of institutions or cultural standards in degenerative decline. Its connotations are sobering rather than judgmental in modern usage; while its root once implied moral fall from type, today "degenerative" carries chiefly clinical weight. It is standard in British and American English, formal register, and indispensable in health writing and everyday discussion of aging and chronic illness.

"Critics described the policy as part of a degenerative spiral in public discourse."
The word "degenerative" comes from Latin degenus — literally "born away from one's kind" — which is why it once carried a harsh moral judgment before medicine claimed it for describing failing joints and fading memory.

Etymology of degenerative
"Degenerative" comes from the Latin verb "degenerare," meaning to depart from one's kind or rank, formed from "de-" (down, away) and "genus" (birth, origin, kind). The related adjective "degenerate" entered English in the late 15th century with both moral and biological senses of having declined from an earlier or better state, and "degenerative" developed from this stem as the form used to describe processes causing such decline. Cognates sharing the same Latin root include "regenerate," "generation," and "degeneration." The word became firmly established in medical vocabulary by the 19th century as physicians sought precise terms for progressively worsening diseases.
How degenerative is actually used
Primarily formal and medical in register; it appears most often in clinical contexts such as "degenerative disc disease." Outside medicine it can sound slightly technical or evaluative when applied to social, cultural, or political decline.
Easily confused with degenerative
"Degenerate" describes something already fallen to a lower moral or physical state (and can be an adjective, noun, or verb), while "degenerative" describes a process that causes progressive deterioration over time.
