For example, the runner or the boxer, so called in virtue of a natural capacity, is not called paronymously from any quality; for there are no names for the capacities in virtue of which these men are said to be qualified as there are for the branches of knowledge in virtue of which men are called boxers or wrestlers with reference to their condition (for we speak of boxing and of wrestling as branches of knowledge, and it is paronymously from them that those in the condition are said to be qualified).
