Abbreviations are short forms of words or phrases. Abbreviations are often used in chatrooms because they are easy to type and they save time. They are also used for texting or direct/instant messaging. Many people also use abbreviations on social media sites. Here are some common abbreviations. Some are shown here in capitals (for example: AFK), but they can also be in small letters (for example: afk).
