ostensive definition
Definition - Defining a term by pointing out examples of it.

Example -
Defining "green" by pointing out or showing green things, such as grass and Martians.

Etymology -
The term was coined by the British logician William Ernest Johnson (1858-1931). It derives from the Latin ostensus, which is the past participle of ostendere, to show.

Oxford English Dictionary -
Its first citation (from Johnson) is from 1921:
"We may now introduce the technical term ‘ostensive’ which will suggest as its opposite the familiar term ‘intensive’.… Imposing a name in the act of indicating, presenting or introducing the object to which the name is to apply,…this it is that constitutes ostensive definition."
(W. E. Johnson Logic I. vi. 94)
