Etymology

Origin of incurable

First recorded in 1300–50; Middle English, from Late Latin incūrābilis; see in- 3, curable

Explanation

Something incurable can't be fixed or healed. Incurable diseases can sometimes be lived with, but they can't be cured. An incurable crush on a movie star means there's no getting over it, and being diagnosed with an incurable illness is always bad news, because no medicine can eliminate it. Your friends might call you an incurable optimist — this means you always see the glass as half-full, and there's no changing your cheerful nature. Incurable combines the prefix in-, "not," and curable, from the Latin cura, "care or concern," and also "means of healing."
