The word ‘leaf’ is not merely a token which may refer to an extension of some vegetal body; it is also a vehicle which covertly conveys the histories, purposes, structure, connotations and implications not only of the lexicon to which it belongs — but also to each term within that lexicon with which it is or may possibly be related. It is not merely a token of reference; it is a method that combines distinguishing, reference, relating, and catalysts toward comprehension.
