...‘oa’ only have one sound each and may not be used at the end of English words.

Except for boa, where the ‘oa’ produces two sounds and is used at the end of an English word. : )

Your excerpt of my post makes it sound grammatically incorrect, lol.

I can’t remember if boa is an exception or if it is not an english word.
