I thought they were two different words. I would never read the "cocoa" out loud as I never knew how to pronounce it.
And until I was 14, I used to think "moderator" (when I read on TPM and forums) was pronounced "modtior". Even sometimes this day I pronounced it habitually in my head as the latter.
And as a child I had to see a speech pathologist. As well as the fact my handwriting was retarded; I was the last to acquire my pen license in Grade 4.
Maybe I suffered minor dyslexia and have overcome it?
