When you mean the GNU Project or GNU software, pronounce GNU as “g-noo”: one syllable, with a hard g, approximately /ɡnuː/. The GNU Project compares it with “grew” with the r replaced by n. This differs from the animal gnu, which is commonly pronounced “new” in American English.
What does GNU stand for?
GNU stands for “GNU’s Not Unix.” It is a recursive acronym: the word GNU appears inside its own expansion. The GNU Project chose the name because it was a real word, a recursive acronym and fun to say. See the project’s explanation at GNU Project: About the GNU Project.
The name refers to a free, Unix-like operating-system project, not to a letter-by-letter reading such as “gee-en-you.”
Why is the G pronounced?
The GNU Project intentionally asks speakers to pronounce the initial g. Its official history describes GNU as one syllable with a hard g; early GNU material also explicitly requested that people pronounce the G to avoid confusion. A hard g is the sound heard in go or grew.

This instruction distinguishes the software name from the usual English pronunciation of the animal that inspired it. The GNU Project’s written guidance is available at Overview of the GNU System, with recordings on its GNU pronunciation page.
GNU software versus the animal
| Reference | Typical pronunciation | Notes |
|---|---|---|
| GNU Project and GNU software | “g-noo”, one syllable; approximately /ɡnuː/ | Hard g, as specified by the GNU Project |
| Animal gnu, common American English | “new”, /nuː/ | The initial g is normally silent |
| Animal gnu, some varieties | “nyoo”, /njuː/ | Recorded as an alternative by Merriam-Webster |
Dictionary entries describe how English speakers say the animal; they do not override the GNU Project’s preferred pronunciation for its software and organization. Compare Cambridge Dictionary, Oxford Advanced American Dictionary and Merriam-Webster.

How to say common GNU names
- GNU Project: “g-noo Project”
- GNU software: “g-noo software”
- GNU/Linux: “g-noo Linux”
- GNU Compiler Collection: “g-noo Compiler Collection”
- GNU General Public License: “g-noo General Public License”
- GNU Hurd: “g-noo Hurd”
The GNU Project uses GNU/Linux for systems combining GNU software with the Linux kernel, although many speakers commonly say simply “Linux.” Its description is at The GNU Operating System and the Free Software Movement.
What about “guh-new”?
“Guh-new” is understandable and appears in some technical writing, but it is not the GNU Project’s stated one-syllable pronunciation. Current GCC documentation uses the respelling “guh-NEW” at GNU Project. That wording conflicts with GNU.org’s explicit “one syllable with a hard g” guidance; the documentation does not establish why the difference exists.
Rank #3
For editing, presentations and ordinary technical conversation, follow the project’s own guidance: “g-noo,” one syllable, hard G.

Yes. Languages adapt foreign sounds to their own phonetic conventions. GNU’s translated pages retain the intentional hard g while using local comparisons—for example, the French page uses “gnou,” and the Portuguese page gives a local analogy. Those forms do not change the English answer for GNU software.
