Define: A Fortiori

(ah-for-she-ory) prep. Derived from Latin, meaning for a still stronger reason; all the more.

Applies to a situation in which a second thing can be inferred to be true if the first thing is true. Therefore, if Abel is too young to serve as administrator, his younger brother Cain is definitely too young.

[Latin, With stronger reason.] 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.
