Etymology
Origin of fortification
1400–50; late Middle English < Late Latin fortificātiōn- (stem of fortificātiō ), equivalent to fortificāt ( us ) fortified ( see fortify, -ate 1) + -iōn- -ion
Explanation
A fortification is a strong wall, building, or other reinforced structure that's used to defend against attack. In medieval times, castle fortifications protected them from invading armies. If you've ever built a fort in your living room or back yard, you know what a fortification is—fort is the shortened form, and the source word is the Latin fortificare, "make strong." Another meaning of fortification is "the act of making something (or someone) stronger," so you might talk about the fortification your math team got from taking an online calculus class or the fortification of your favorite breakfast cereal with vitamins.
