Able to be passed down from parents to their children, often referring to traits or characteristics.
Certain diseases are heritable, meaning they can be passed from parents to their offspring.
Heritable is formed from "herit" (from Old French *heritier*, meaning to inherit) and "-able" (meaning capable of). The word "heritable" refers to something that is capable of being inherited.
Think of something that is 'capable of being inherited' — 'herit' relates to inheritance, and '-able' means capable.
