I'm writing a paper in which I need to refer to the two parts of a conditional probability $P(A|B)$. Just to be clear, in the context of my paper, I cannot simply write "$A$ conditioned on / given $B$". This is because the probability function is actually defined over multiple random variables and the partition to $A$ and $B$ is not constant but depend on other factors, such as special properties for a variable to belong to either $A$ or $B$.
After searching for a while I couldn't find any consistent answers on the matter, where the closest I've encounter were references to $B$ as the "conditional part". At the moment, I'm using as placeholders "conditional" and "consequent" parts (also considered "antecedent" instead of "conditional"), but I could barely find other references using the latter. Someone has suggested to me to use the "left-side" and "right-side", but it can conflict with the description of equations.
If there are any proper names to these parts, or at least better names than the above, then I would really appreciate it.
