“Every exit sign in every building is a conjugated Latin verb. He exits. She exits. Third person singular—captured in red letters.”
Exit is Latin. It's the third person singular present tense of exire, 'to go out'—the same root as 'exodus.' In Latin, exit means literally 'he/she/it goes out.' Roman playwrights used it in stage directions: when an actor left the stage, the script noted exit, the technical marker that a character had departed the scene.
By the Renaissance, theater companies across Europe adopted the convention. Stage directions were written in Latin even when the play was in English or French. Exit remained the standard notation. Every actor knew: when the script says exit, you walk offstage. It was a verb frozen into a stage direction.
By the 1800s, the noun form developed. An exit became the door or passage through which you leave. Exit signs appeared in theaters, then in public buildings, then everywhere. The word had transformed from a verb (to go out) to a noun (the place where you go out), and it kept its Latin form because the convention was already two hundred years old.
Now exit appears on every evacuation sign, every doorway, every emergency route in the world. It's the most universally recognized Latin word on earth—more common than 'et cetera' or 'etc.,' more universal than 'vice versa.' No one remembers it's a verb. We've turned Roman grammar into safety infrastructure.

Exit is a verb we've treated as a noun for so long that it feels like a noun. We've made it into infrastructure. No one steps through an exit and thinks 'he or she goes out'—they think 'this is the door.' The grammar has faded. Only the function remains.
Latin survives not in libraries but in red letters on walls. The language of empire became the language of escape.
