What does unhealthily mean?
“Unhealthily” is an adverb meaning “in an unhealthy manner” or “to an unhealthy or excessive degree.” It is commonly used to intensify descriptions of physical condition, such as someone being unhealthily thin or pale, and to characterize dependence that has become excessive, as in a market being unhealthily dependent on one commodity. The word often carries a warning implication: what is being described may not be merely unfortunate or unusual but actively harmful. Because it is formed from “unhealthy” with the adverbial ending “-ly,” it can apply wherever manner or degree is being expressed. In editorial and analytical writing, it is useful for identifying risks that ordinary adjectives such as “poor” or “excessive” may not convey as clearly. Its meaning is generally the same in British and American English.
adverbIn a manner that is harmful to health, or to an excessive or unhealthy degree.
- In a way that is harmful to health.
- To an excessive or unhealthy degree.
"He was unhealthily thin and had been unhealthily dependent on caffeine for years."
"The horse was unhealthily thin by the time it reached the farm."
"The economy became unhealthily dependent on a single industry."
Add “un-” and an ordinary observation becomes a warning: pale, thin, or dependent can describe a person or system, but “unhealthily” signals that the condition has crossed into excess.
