FAQ
Frequently Asked Questions
Yes, but it is the precise medical term for a specific type of widespread, often infectious, rash. In everyday language, 'rash' is far more common.
In British English: /ˌɛksænˈθiːmə/ (eks-an-THEE-muh). In American English, the first 'x' can sound more like /ɡz/: /ˌɛɡzænˈθiːmə/ (egz-an-THEE-muh).
Very rarely. It might be used figuratively in literary or journalistic contexts to describe a sudden 'outbreak' of something (e.g., 'an exanthema of protests'), but this is highly stylistic and uncommon.
The two most accepted plurals are 'exanthemata' (following the Greek/Latin origin) and the anglicized 'exanthems'. 'Exanthemas' is also seen but is less standard.
