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. The particular case I want to ask about concerns the 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 divisors.

Question: What are your suggestions for the names of those more specific tags which could replace 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.
