fontology: n.

[XEROX PARC] The body of knowledge dealing with the construction and use of new fonts (e.g., for window systems and typesetting software). It has been said that fontology recapitulates file-ogeny.

[Unfortunately, this reference to the embryological dictum that “Ontogeny recapitulates phylogeny” is not merely a joke. On the Macintosh, for example, System 7 has to go through contortions to compensate for an earlier design error that created a whole different set of abstractions for fonts parallel to ‘files’ and ‘folders’ —ESR]
