Abbreviations are short forms of words used in English. They help us say long words quickly. For example, “TV” is an abbreviation for “television.” We use abbreviations a lot because they save time. They’ve been around for a long time, even in old writings. Abbreviations are important in English. When we read or write, we often see them. They help make things clear and fast. If you want to understand English well, knowing about abbreviations is helpful.
