The language is used differently, depending on what it is used and which audience it is intended for. Normal, ordinary language among small groups is fundamentally different from the sophisticated language that reaches a larger group of people. There are many different groups within the formal languages, depending on what we are talking about. This is true for all languages, so we need to ask English what is the difference between business English and English.
Two forms of English can be defined as follows. In English for business use, English is used for very practical purposes; ie you are looking for money. This form deals with commercial matters. Literary English is almost completely counterproductive. It focuses on artistic or idealistic issues and does not care about finance.
Since business people in English speak about money, the vocabulary they use consists mostly of words describing financial matters. They can use the accounting and economics computing terms that the average person would not understand. On the other hand, literary English will not usually use such words, but will use a larger sequence, as it has a wider range of powers, so it has to write more words on several things.
Styles will be different. English literary forms are more floral and more ornate, and sentences are often longer. Not only what they consider important, but also to say it is noteworthy. In contrast, business English will use sentences that are short and accurate.
English-speaking users are primarily native speakers of English, or if English is not their mother tongue, they have spent many years studying developing advanced facilities. On the other hand, because today's business is more global than in the past, many business English users have only basic knowledge and are able to understand and pursue a primitive conversation. It's easier to use, as many users do not have the English language skills.
English used to describe financial matters uses more statistics and figures and is much more analytical. She's trying to describe something, or if it gets arguable, she will build up her case using the hard data. We hope to see a lot of numbers in it. In literary English, the numbers rarely appear. This is much more subjective and more work on emotional level.
In the last century, the use of both types of English has increased, and this growth is likely to increase. The global nature of the global economy means that people from all corners of the earth can communicate with each other, and since English is so widespread, business English is widely used. An interest in English arts and folk arts, especially the mass media, such as films and television, supports the spread of English literary variants.
English is the world's leading popular language. People are still interested in doing business and expressing non-practical issues.
