GNU stands for Gnu's Not Unix. It's a recursive acronym.
In essence, GNU is a free and open-source operating system. The GNU project was launched in 1984 by Richard Stallman with the goal of creating a complete Unix-like operating system that is free software. The name "GNU" itself is a playful recursive acronym, emphasizing the project's independence from Unix while maintaining compatibility. It is pronounced "g-noo," like the African antelope.
