Even though i don't really like Ketchup, I still spell it Ketchup I don't get how something spelled Catsup could sound the same as Ketchup now the word just sounds weird to me
Most people I know spell it ketchup or pronounce it so. Catsup sounds too much to me like 'cat soup' lol... On the other hand, in school I was told that the correct form is actually 'catsup'...
I say ketchup and after reading the link scarlett posted, I have more reasons to say ketchup. I like Heinz ketchup, better than Hunt's, Hunt's is too watery for me. So Ketchup it is.
