  • A Fortiori
A Fortiori
A Fortiori is the Latin for “with even stronger reason,” which applies to a situation in which if one thing is true then it can be inferred that a second thing is even more certainly true. For example, if “A” is too young to serve as an administrator, then A’s younger brother “B” certainly is too young. This phrase is used in logic to denote an argument to the effect that because one ascertained fact exists, therefore another which is included in it or analogous to it and is less improbable, unusual, or surprising must also exist.
