I'm not sure if this goes here, sorry if it doesn't
For the past several years I have enjoyed the differences twix American and British English and I endevour to use the British spellings of words, i.e. Colour, Favourite, and to drop those annoying Zs', i.e.Realise, Scrutinise. Is the British spelling the "correct" spelling? Or is the the American spelling just further evolution of our language?
And lastly, Tire v/s Tyre, I am not sure where the difference came from.
Thanks,
Eric
