How do you pronounce gagnan?

There is no word "gagnan" in the English language, so it's impossible to say how it is pronounced.

It's possible that:

* It's a misspelling: Perhaps you meant a different word, like "gaggle", "gaga", or "ganan".

* It's a foreign word: If it's from another language, the pronunciation would depend on that language's rules. Please provide more context about the word's origin!
