The word 'whiten' means to make something white or to become white. For example, you can whiten your teeth using a special toothpaste or whitening strips. You can also whiten clothes by washing them with bleach. The word can also be used to describe the process of making something appear lighter or brighter, such as whitening a room by painting the walls a light color. It is important to note that the word 'whiten' should only be used to describe things that are actually becoming white or lighter in color, and not used in a discriminatory or offensive way.
