Why Don't They? Math Vision No. 2

I envision a dictionary of terms used in mathematics. It should be linked back until undefined terms are reached. Synonyms could be defined by reference to a single term. English should be the base with terms in other languages (esp. German and French) defined as synonyms. Common terms used in examples might be included (e.g. orange = object, oranges = objects, apples = objects).

Measurement terms would need careful treatment:

yard = 36 inches
yard = unit of distance
Would distance need to be an undefined term?

A seperate list should be made of undefined terms.

Naive Lie Theory Note 3

Notation and definitions are introduced in a rather haphazard manner and this is complicated by an incomplete index.
