From Old French 'fort' meaning strong; also a place-based surname.
Fort comes from Old French fort, meaning strong, and it also works as a place-based surname. That makes it one of the bluntest and most forceful names in this set: short, direct, and semantically obvious.
It carries a sense of fortification and resilience just by being spoken. As a given name, Fort feels austere and unconventional, almost architectural in its simplicity. It has the virtue-name energy of strength without the sentimental softness that sometimes accompanies such words. The result is a name that seems compact, emphatic, and unusually self-assured.
