What does exacerbate mean?
Exacerbate is a formal verb meaning to make a bad situation, problem, or feeling worse or more intense. It is most often used with abstract nouns such as a crisis, a conflict, symptoms, inequality, or tension: 'The drought exacerbated food shortages across the region.' The word implies not that something bad has been created, but that something already negative has been deepened or aggravated — which is why it appears so frequently in news reporting, medical writing, and policy analysis. It is standard in both British and American English and sits comfortably in professional and academic registers, though it is equally at home in serious journalism. Its connotation is unambiguously negative; one cannot exacerbate a benefit. A useful companion noun is 'exacerbation,' as in 'an exacerbation of symptoms.' Learners sometimes confuse it with 'exasperate,' which means to annoy. Knowing 'exacerbate' gives writers a precise, authoritative way to describe how problems compound rather than simply occur.

Despite sounding like it should mean 'to frustrate', 'exacerbate' literally traces back to a Latin word meaning 'to make bitterly harsh' — from 'acerbus', the same root that gives us 'acerbic'.

Etymology of exacerbate
Exacerbate derives from the Latin verb 'exacerbare,' formed from 'ex-' (intensive) plus 'acerbus,' meaning bitter, harsh, or sour. It entered English in the early 17th century, initially used in medical contexts to describe the worsening of disease or pain before broadening to general use. The same Latin root 'acerbus' also yields English words such as 'acerbic' and 'acerbity,' all sharing the core sense of bitterness or sharpness.
