Actually, yogurt in Britain is slightly confusing, the spelling I mean, not the yougurt......anyway, it's got two alternative spellings. It can still be spelt with an 'h' as in yoghurt, but is uually spely yogurt! The English language has so many vagaries!
Mizz I passed this test too, being English however and living in the USA I often have to think about spelling, I try to spell the USA way (when in Rome) but often in the heat of typing my childhood spelling lessons rule!
Cheque or Check
Colour or Color
Yogourt or Yogurt
to name just a couple!
And of course there are no such words as Palavar or Malarky here!
