Caboz is one of my favorite of Michael's mispronunciations. He has said 'caboz' since he started talking instead of the word 'because'. It is pronounced /kuh/ /boz/. The 'o' is pronounced as a short o (i dont know how to create that marking) I love it so much, I let it go on way longer than I should. The thing is, he has such an advanced vocabulary, that hearing the word becoz helped me remember how old he truly is/was. Very recently, he said the word and I felt a little pinch of guilt, so I opened my mouth to tell him the word was really 'because' and he looked at me (I'm pretty sure he would have rolled his eyes if he were a little older). His exact words were, "I know the word is really because its just caboz I have said caboz for so long that it comes out of my mouth instead of because."
He makes my heart so happy! As happy as a boy at a bakery who can pick out anything he wants!
