DEFINITION of -able

Forms adjectives: capable of (being), able to; -able is a productive adjectival suffix in medical terminology that transforms verbs and nouns into adjectives expressing capability, susceptibility, or fitness for a particular action or state. When attached to a medical term, it indicates that something can undergo, receive, or be subjected to the action described by the root word. In clinical documentation and medical coding, this suffix frequently appears in descriptions of tissue characteristics, treatment possibilities, and physiological capacities. The suffix conveys passive capability—meaning the subject can receive or undergo an action rather than actively performing it.
