degenerative

Etymology

It is formed from English degenerate + -ive,^[2][3][4] or, in the OED's analysis, from Latin dēgenerāt-, the past participial stem of dēgenerō (“to fall away from an earlier standard, deteriorate”), with the English suffix -ive; the OED compares Medieval Latin degenerativus, recorded from 1672.^[5] The Latin verb is from dēgener (“low-born, unworthy of one's ancestors”), from dē- and genus (“race, kind”),^[5][2] from Proto-Indo-European *gene- (“to give birth, beget”).^[2]

Earliest recorded meaning

Causing or marked by a decline in the qualities thought normal or desirable; tending to deteriorate: before 1680, in S. Charnock's Several Discourses upon the Existence and Attributes of God.^[5] Etymonline and the Merriam-Webster Unabridged date the word to about 1846,^[2][6] and Dictionary.com to 1840–50.^[3]

Semantic evolution

The general sense of falling below a normal standard came first,^[5] following the older adjective and verb degenerate.^[2] A medical use, of deterioration in the structure or function of parts of the body, is recorded from 1754, in a translation of Haller's Physiology,^[5] and this is now the main sense, above all in degenerative disease, one marked by progressive, often irreversible loss of tissue or function.^[4][7][8]
