Word count is a way of counting how many words are in something. You can do it by hand (counting each word by saying it out loud or writing it down) or with a computer. With a computer, you can quickly count how many words are in a document, story, or website. Word count is often used to make sure that something is the right length, like an essay or a story. It can also be used to compare two pieces of writing and see which one is longer.
