TITLE: Is there such a thing as a mathematical thesaurus?
QUESTION [23 upvotes]: I want this for two reasons:

When writing proofs, I am constantly in need of synonyms of basic words like thus, there exists, for all, such as, contains, etc.
A lot of mathematical concepts have multiple names, e.g. abelianization vs derived quotient, vanishes vs goes to $0$, and so on.

A big list of either of these types of synonyms would help improve the flow of my mathematical writing.  Also, the latter case would familiarize me with alternative terminology I may run into later.
Does anything like this exist?

REPLY [10 votes]: There is a very comprehensive (at least very long!) "Handbook of Mathematical Discourse" which you can find here.
Under the various topics they list some synonyms, but I can't vouch for its completeness or accuracy. Also, it is more of a dictionary or encyclopedia than a pure thesaurus.
EDIT: Another question on Math.SE asks a similar question and one of the answers points to this online encyclopedia. It seems, however, that this one might be of limited use as a thesaurus. After a few tries it looks like synonyms are rarely included.
