Ostensive definition

Definition by example

An ostensive definition conveys the meaning of a term by pointing out examples. This type of definition is often used where the term is difficult to define verbally, either because the words will not be understood or because of the nature of the term. It is usually accompanied with a gesture pointing to the object serving as an example, and for this reason is also often referred to as "definition by point ".
