Ceteris paribus and mutatis mutandis.
I came across ceteris paribus in reading the Wikipedia entry for “Price elasticity of demand”. Ceteris paribus “is a Latin phrase meaning ‘with other things the same’ or ‘other things being equal or held constant.'”1 Ceteris means “the other” and paribus means “equal”.
The Wikipedia page lists two types of ceteris paribus clauses: hypothetical and substantive. Among the substantive, there are the further hyponyms: temporal isolation and causal isolation. I need to read more into all of this to understand it more.
Ceteris paribus is shortened by writing cet. par. or c.p. It is considered New Latin, due to it originating in academic works well after the Roman Empire.
Mutatis mutandis means “‘the necessary changes having been made’ or ‘once the necessary changes have been made.'” It’s Latin directly translates to “with the changes changed.”
I don’t know if these words are unnecessarily pretentious or absurdly useful. Either way, it’s important to know them.

- The Wikipedia page for ceteris paribus has a lot of vocabulary/ideas I’m not familiar with. I need to read into this more: more about the difference between “fundamental science” and “special sciences”, what it means to have a “logical empiricist view of science”, what are its opposites, and what is the differences in mechanistic models vs. law models? ↩
