@JTT,
Quote: Hundreds of spelling variations occur between dialects of English.
I should have thought there are at least hundreds of thousands if one takes the trouble to indulge in the affectation of trying to reproduce them.
There is a considerable difference between how "hurt" is spoken where I live and how it is spoken 10 miles away. So also with many other words as I know from a fellow boozer who came from there. How it might be possible to render such differences in print for all the places in England is a problem I wouldn't care to attempt to solve.
People who attempt dialect writing are stumped on most of the words they employ.
And meanings of words vary as well. As also do choices of words to designate the same things.
I'll revise my previous estimate on superficially considering the matter. It must be hundreds of millions from a scientific point of view. At least.
From my childhood reading I had developed a pronunciation of "orangutan". I was quite surprised later that wildlife programmes on the BBC pronounced the word markedly differently. If I am called upon to say the word now I have to stop momentarily and rehearse the BBC version before saying it.
"ooze geeten ur skidsy trollies darn nah".
Maybe it's infinite. "Hundreds" is ridiculous JT and objective proof that you haven't put much thought into what you say.
