It's no surprise that English, as today's leading global language, is spoken or written with such a wide range of informality and formality like dialects, slang, argot, gobbledygook, jargon, legalese, and academese. Even within countries of predominantly native English speakers, acceptable variations in vocabulary, spellings, idioms, and syntax can become so pronounced as to constitute a Babel of tongues.
