“The words used in common usage should be those that are unambiguously understood by all English-speaking people, . . “
Does that mean all English-speaking people world-wide, or only in the States. I ask because there might be 250 million people in the USA who have quit using some expressions, and 250 million English speakers elsewhere who still use them. And then, of course, when you add West Virginians and Carolinians to the foreign English Speakers who still use “cousin” in the more general, looser sense, (Ha!) Then W. Virginia and Carolina belong to the majority, and are no longer so “isolated.” It is only further proof that Americans should learn English, and quit worrying about archaic words in a KJB. LEARN the words. Use them. Our Chinese students use the KJB and use many of the expression in their everyday English. Its quite nice. When they meet other foreigners, they are always complimented and people are amazed at how they are able to use KJB English.
Does that mean all English-speaking people world-wide, or only in the States Look, if basic English is incomprehensible to all English-speaking people, then English should be reclassified as different but related languages. One thing is certain: no one speaks the 17th century version of British English found in KJV.
