What does fortification mean?
Fortification refers both to the structures built to defend a place and to the process of strengthening something against attack or deficiency. In its most familiar sense, a fortification is a physical work of defense — a wall, rampart, moat, or fort — designed to protect a city, border, or stronghold from invaders. Famous examples range from Hadrian's Wall to the star-shaped bastions of early modern Europe. The word also extends beyond the battlefield: engineers speak of the fortification of a building's foundations, and food scientists use 'fortification' to describe adding vitamins or minerals to staples like flour, salt, or milk. Derived from the Latin fortis, meaning strong, the term inherently connotes deliberate reinforcement and protection. Whether describing castle walls or enriched bread, fortification always signals an intentional act of making something stronger and more resistant to harm.

Etymology of fortification
Fortification derives from the Latin fortificare, formed from fortis ('strong') combined with facere ('to make'), literally meaning 'to make strong'. The word entered English via Middle French in the late Middle Ages / early modern period, coinciding with advances in military architecture. It shares this Latin root with related words such as fortify, fortress, fort, and forte, all of which trace back to the same notion of strength.
