True, Peace.

Some years ago, I forget his name, a well-educated Englishman commented on the lack of diversity in language as he crossed the country. By this, he was referring to the lack of variety in regional speech compared with England, where each area had usages that distinguished it from others.
This has changed, as regional usages and dialects are lost in England.
In each area, however, the number of words commonly used is limited; thus no more words are used by an 'average' Englishman than the 'average' North American.

One area of difference is in the use of sounds like "Hmmm;" depending on intonation, an Englishman can convey many more meanings than a North American, from agreement to provisional acceptance to complete rejection; from amazement to disgust.
