What is a suffix for constant?

There isn't a single, universally accepted suffix for "constant". However, depending on the context, several suffixes can be used:

In programming:

* _const (e.g., `my_variable_const`)

* Const (e.g., `myVariableConst`)

* C (e.g., `myVariableC`)

In mathematics and physics:

* k (e.g., `k` for Boltzmann's constant)

* c (e.g., `c` for the speed of light)

Other possible suffixes:

* -ic (e.g., "atmospheric" - indicating something related to the atmosphere)

* -al (e.g., "seasonal" - indicating something related to the season)

The specific suffix used often depends on the specific context and the conventions within that field.
