IPA: //nɪˈstætɪn//
KK: /nɪˈstætɪn/
A type of medicine used to treat infections caused by fungi, particularly effective against yeast infections.
The doctor prescribed nystatin to help clear up the fungal infection.
Nystatin is derived from "Nystatin" (a coined term from the name of the New York State Department of Health, where it was discovered) and the suffix "-in" (used in chemistry to denote substances). The word refers to a substance derived from a specific source, in this case, an antifungal medication.
Think of 'Nystatin' as a name that comes from a specific place (New York) where this antifungal was discovered, and the '-in' indicates it's a substance.
