Synonym discussion
Sense: adjective/1
Curable is the strongest of these words because it suggests the illness can be fully removed, not merely controlled. Treatable is broader: doctors may be able to reduce pain or slow a disease, even when it does not disappear completely. Reversible is used when a harmful condition can be changed back, such as reversible hearing loss or reversible damage, so it is not limited to disease. Healable is less common in medical writing and often describes wounds, skin, or even emotional hurt rather than a diagnosed illness. In practice, a curable infection should go away with proper care, while a treatable one may still need long-term management.

Etymology
Curable is built from cure and the suffix -able, which means 'able to be.' Cure came into English through Old French from the Latin word cura, meaning 'care' or 'treatment.' The adjective developed to describe illnesses or conditions that can be made well by medical help.
