What is the terminology for $a$ in $x>a$?

Question

In an expression like $$x>a,$$ what do I call $a$? And how to distinguish it from $b$ in $$x\geq b.$$ Is there some standard terminology?

Answer 1

Extracting from the comments:

I think that the words "majorant" (for $x$) and "minorant" (for $a$) would suffice, and that you could use "strict majorant" for $x$ in in $x > a$ and "weak majorant" when you only know that $x \ge a$, but those might be confusing to a reader.

In fact, if I were writing something like this, I'd say

"So we see that $x > a$. Calling $x$ the "majorant" and $a$ the minorant in such expressions, we more generally see that ..."

i.e., give an inline gloss on the words you want to use henceforth.
