Exit

Common senses and distinguishing features

"Exit" can describe a physical doorway or route used for ordinary movement, an emergency egress designed for rapid evacuation, or a marked sign indicating the way out. In theatre, a stage direction such as "exit" (singular) or "exeunt" (plural) tells performers to leave the stage. In everyday usage, the nuance between "exit," "egress," and "evacuate" depends on context: "egress" often appears in technical or legal texts, while "evacuate" implies urgency.

Computing and technical uses

In computing, "exit" refers to the termination of a program or process. Programs return an exit status or code on termination; by convention, zero indicates success and nonzero values signal errors or particular conditions. Many operating systems provide an exit system call or function to end execution and return status to the parent process.

Business, policy and cultural meanings

In business and finance, an "exit" is a planned end to an investment—commonly an acquisition, initial public offering, or other liquidity event. In politics and public discourse, "exit" can label a country or entity leaving a union or agreement, and in polling, "exit polls" refer to surveys of voters as they leave polling places.

Importance and practical considerations

Exits matter for safety, accessibility and workflow. Building codes prescribe exits, lighting and signage to enable safe evacuation; theaters and software define clear exit procedures; and organizations plan exit strategies to manage transitions. Recognizing which sense of "exit" applies avoids confusion and supports clearer planning in design, law, technology and communication.
