IPA: /ɪnˈkjʊərəblɪ/

In a way that cannot be cured or fixed; often used to describe a condition or situation that is permanent and unchangeable.
He was diagnosed with an incurably disease, which meant he would need lifelong care.
Incurably → It is formed from "in-" (meaning not) and "curare" (meaning to care for or heal) combined with the suffix "-able" (meaning capable of). The word "incurably" means not capable of being healed or cared for, indicating a condition that cannot be cured.
Think of 'not' ('in-') being able to 'heal' ('curare') something — that's why incurably means it cannot be healed.
