Syn. -- Definition, Explanation, Description.

It is not therefore true, though often said, that description is only an extended definition. “Logicians distinguish definitions into essential and accidental. An essential definition states what are regarded as the constituent parts of the essence of that which is to be defined; and an accidental definition lays down what are regarded as circumstances belonging to it, viz., properties or accidents, such as causes, effects, etc.” Whately.
