"Wear out" is a phrase used when something becomes too old, tired or beaten-up to function properly anymore. For example, your shoes might "wear out" if you wear them every day for months on end, and they become so worn and ragged that they fall apart. Similarly, a machine or appliance might "wear out" if it's used too much and stops working well. It can also be used to describe someone who becomes exhausted after doing something for a long time.
