    And, no matter what … we will muddle along with our different spellings within the English group of dialects. Thing is, is there also a subtle difference in the nominally “correct” pronunciation in countries choosing fundamentally different spellings?

    You know … “schedule” in Britain is often “SHED-jyool”, whereas in all of America it is “SKED-yool” or “SKED-jule” (with the later being more common). I’m good at IPA, sorry.

    Might the British themselves say ‘cauterise’ more like “KOH-ter-IYS” or “KOH-ter-IYZ”? It would be nice to know!
