Q: I was discussing well-being this morning and wondered about its antonym. AI says “the opposite of wellbeing is often considered to be illbeing, which refers to a state of poor health or unhappiness.” Do you have any thoughts about this?
A: You can find “ill-being” in several standard dictionaries. Merriam-Webster, for example, defines it as “a condition of being deficient in health, happiness, or prosperity,” and American Heritage as “lack of prosperity, happiness, or health.
The Oxford English Dictionary, an etymological reference, says it refers to an “ ‘ill’ or unprosperous condition; employed as the antithesis of well-being.” Both terms are usually hyphenated now.
The OED indicates that “ill-being” is relatively rare, with “about 0.02 occurrences per million words in modern written English.”
As for the more common “well-being,” Oxford defines it as “the state of being healthy, happy, or prosperous; physical, psychological, or moral welfare.”
A search for “ill-being” and “well-being” in Google’s Ngram viewer, which compares words and phrases in digitized books, confirms the rarity of “ill-being.” In fact, the OED has only two examples of the usage, both from the 19th century:
- “The test of vital well-being or illbeing to a generation.” From On Heroes, Hero-Worship, and the Heroic in History (1841), by Thomas Carlyle. (In later edited editions, both terms are either hyphenated or unhyphenated.)
- “Philanthropists … insuring the future ill-being of men while eagerly pursuing their present well-being.” From Herbert Spencer’s The Man Versus the State (1884), a work of political theory combining four articles published earlier in the year in the Contemporary Review, a British journal.
Interestingly, we found these much older, archaic senses of “well-being” and “ill-being” while looking into your question: “being blessed by God” and “being damned by God.” Both senses appear in this passage from Fifty Sermons, Preached by That Learned and Reverend Divine, John Donne (1649):
“Our Esse, our Being, is from Gods saying, Dixit & facti, God spoke, and we were made: our Bene esse, our well-being, is from Gods saying too; Bene-dicit God blesses us, in speaking gratiously to us. Even our ill-being, our condemnation is from Gods saying also: for Malediction is Damnation. So far God hath gone with us that way, as that our Being, our well-being, our ill-being is from his saying.”
The OED doesn’t include those two archaic meanings of “well-being” and “ill-being,” but it does cite several obsolete or archaic uses of “ill” and “well” as applied to persons of either evil or good character.
Although “ill-being” is relatively rare now, it does appear once in a while, as in this title of a recent research article: “The nature of the relation between mental well-being and ill-being” (Nature Human Behaviour, December 2025).
