The word 'which' is used to refer to a specific thing or things out of a group or list. For example, "Which book do you want to read?" or "Which color do you prefer?" You can use 'which' when there are options to choose from, and you want to know which one the person wants or is referring to. It's important to note that 'which' is used when the options are limited and well-defined.
