IPA: /ʌnˈkjʊəd/
KK: /ʌnˈkjʊrd/
Not treated or healed, especially in reference to a disease or condition that has not been resolved.
The doctor explained that the infection was still uncured and required further treatment.
Uncured → It is formed from "un-" (meaning not) and "cure" (from Latin "cura", meaning care or treatment). The word "uncured" means not treated or not healed.
Think of 'not' ('un-') having received 'care' ('cura') — that's why uncured means something that hasn't been treated.
