English speaking people have never been really homogeneous in their use of the English language. Today, if you travel extensively in the British Isles, you notice differences in pronunciation and ‘vocabulary from shire and shire, or even if your ear is good enough, from town to town. In London alone you can find  tremendous diversity in the varieties of English. In the United & States, likewise, the language differs somewhat from place to place and from one social *“class” to another. Many New Yorkers don’t 3 Spronounce. words as Chicagoans do, and in Denver people don’t  sound like those in Chicago. In some parts of the Southwest,Spanish influence shows up in the vocabulary; elsewhere, Germans and others have affected the English language.
