So I was a student of English was taught English right on the border between the US and Canada. My husband (who is from the Southwestern states) was reading something I wrote where I used the spelling hiccough and laughed at the spelling as he had not yet encountered it. I was wondering if there was any regionality behind how one spelling gets chosen over another in how the spelling is taught. I actually know and use both spellings (I don't know why I choose one over another in any particular circumstance).
To draw an analogy, all over BC Canada, you find "cheque" spelled as I show here. However, all over Washington State US, you find it spelled, "check." Pronunciation is the same. I'm just wondering if any one knows if there is a similarity in regard to hiccup/hiccough.
