Sloth A
I was reading about logic and came across the term biconditional.
Sloth B
Oh, I think I remember that from class! It's like when two statements depend on each other, right?

Root Explanation

Biconditional → It is formed from "bi-" (meaning two) and "conditional" (from Latin "conditio", meaning condition). The word refers to a logical statement that is true if both conditions are either true or false, hence involving two conditions.

Memory Tip

Think of 'two' ('bi-') conditions that must be true or false together — that's what biconditional means.
