morbid

Etymology

It is borrowed from Latin morbidus (“diseased, sick, causing disease, unhealthy”),^[2][3][4][5] from morbus (“disease”) and the suffix -idus.^[2][6] Barnhart allows a passage through French morbide but thinks direct borrowing from Latin more likely;^[7] Skeat derived it from the French.^[8] The further origin of morbus is unknown to the OED.^[2] Etymonline reports de Vaan's suggestion that it meant "looking like death", from the root of morior (“to die”), from Proto-Indo-European *mer- (“to rub away, harm; to die”), or else that it is a non-Indo-European word;^[4] Skeat and Weekley also linked it with the Latin verb for "to die".^[8][9] Klein instead explains it as "that which consumes", from the same root in the sense "to wear away, consume", and compares Ancient Greek μαραίνειν (maraínein, “to consume, exhaust”),^[10] which Merriam-Webster also cites as akin.^[11] Middle English had morbous (“diseased”), from Latin morbosus.^[4]

Earliest recorded meaning

Of the nature of disease, or indicative of it: 1656, in Henry More's Enthusiasmus Triumphatus.^[2][7][11] The Oxford Dictionary of Word Origins likewise dates the word to the mid 17th century, in the sense "indicative of disease".^[12][5]

Semantic evolution

Of a person or a part of the body, morbid meant "diseased" from 1668,^[2] and Johnson (1755) defined it as "diseased; in a state contrary to health".^[13] The figurative sense, of a mind given to excessive gloom, appears in 1775,^[2] and the Oxford Dictionary of Word Origins places the shift to "gloomy, unhealthy" in the late 18th century;^[12] Barnhart first finds it of ideas and mental states in 1834, though morbidness of mind is recorded in 1681.^[7] In later use the word came to mean an unhealthy fascination with death, disease and other gruesome things.^[2][14] Weekley compared the figurative use of French maladif.^[9] In painting the word was briefly used (1728) of flesh tints painted with morbidezza, perhaps after Italian morbido.^[2] The medical sense survives in morbid anatomy, the study of diseased organs and tissues.^[6][11]
