A button is a small, often round, object that can be pressed or switched to operate something. It is commonly found on clothing, electronic devices and machines. For example, you can use a button to turn on a light or start a machine, and on clothing to fasten or unfasten it. The word 'button' can also be used metaphorically to describe something that looks like a button or is used in the same way, such as a button on a webpage that you click with your mouse.
