Question about spelling

[Whall10]

Just wondering if this word is spelt pronunciation or pronounciation?

I'm seeing the latter a lot, however it doesn't seem correct to me.

The former - pronunciation.

Thank you

Now, the people who are slagging the 'pronounciation' on the baby name threads need to check their spelling! It was becoming so common, I thought I had it wrong!
