Is it 'pronounciation' or 'pronunciation'?

The correct spelling is: pronunciation ✔

The confusion is understandable, as both the noun pronunciation and the verb pronounce come from the same Latin root.

However, while pronounce is spelled with an ou between the two n's and is pronounced like this: prəˈnaʊns, pronunciation is spelled with just a u between the two n's and is pronounced with a short /ʌ/ sound like this: prəˌnʌn.siˈeɪ.ʃən
