A few names are used in different subjects in mathematics with completely distinct meanings. A couple of common examples are "spectrum" and "regular". Sometimes, this creates problems with tags on MathOverflow, as is explained in some of the answers to the question http://meta.mathoverflow.net/questions/862/help-cleanup-tags. Specifically, I want to ask about the tag [tag:divisors], which is used for questions concerning:

- divisibility in the integers or in rings, and
- divisors in algebraic geometry.

It may be desirable then to use two more specific tags to replace [tag:divisors].

> **Question:** What are your suggestions for the names of those more specific tags which could replace the tag [tag:divisors]?

> **Generalized question:** Do you suggest any general strategies for naming tags which distinguish the subjects of origin? A hypothetical example is: name tags which distinguish "spectrum" in functional analysis from "spectrum" in algebraic topology.

Just to be clear, I do not intend this question to become a discussion concerning the necessity or desirability of more specific tags.
