Slang is a popular, less official and often very current form of language. It is an important part of a living language and is constantly changing as language changes. Slang is often playful, direct and sometimes less respectful than the more official and traditional version of language. There are many reasons that promote the development of slang. For example, the Internet has helped create a whole new kind of computer-related slang. Young people often develop the latest slang. Different professions often have their own slang as well. No matter how well you speak English, there are always new and interesting slang words to discover. There are entire dictionaries for describing slang. Many experts do not even agree on what is and what is not slang. Often slang words later become a part of officially accepted language. Official or not, slang is an energetic and exciting part of the American language that continues to change.
