sorry for the confusion. We Americanskies are ornery that way.
Someone will probably come along and give you more nuanced interpretations than me, but anyway........
I suppose you could call hushpuppies a fritter, but they are more "shaped", if that makes sense. "Fritters", on the other hand, can be a little more free-form, with little crusty greasy edges that you just love to bite off before you dig in to the main event.
I know there's supposed to be a difference betw. yams and sweet potatoes, but to me they taste the same and I prepare them the same way. I wouldn't lose any sleep over trying to differentiate.
Does this help?
