IPA: /ɪnˈkjʊərəbl/
KK: /ɪnˈkjʊrəbəl/
Something that cannot be cured or changed, often referring to diseases or habits that are permanent.
Despite trying many treatments, the doctors said his condition was incurable.
Incurable → It is formed from "in-" (meaning not) and "curare" (meaning to care for or heal). The word "incurable" means not able to be healed or cared for, indicating a condition that cannot be cured.
Think of 'not' ('in-') being able to 'heal' ('curare') something — that's why incurable means something that cannot be healed.
