IPA: //ʌnˈkjʊərəbl//
KK: /ʌnˈkjʊrəbəl/
Not able to be cured or healed; a condition that cannot be treated successfully.
The doctor explained that the disease was uncureable and required ongoing management.
Uncurable → It is formed from "un-" (meaning not) and "curable" (from Latin "curabilis", meaning able to be cured). The word "uncurable" means not able to be cured or treated.
Think of 'not' ('un-') being added to 'able to be cured' ('curable') — that's why 'uncurable' means something that cannot be cured.
