wax

Wax is a solid material made of animal fat.

Example: A candle is made of wax and a thick thread and has a flame on top.

If you wax something, you put wax on it, for example, a car.

Example: She waxed her car to make the paint shine brightly.

When something waxes, it means that it gets bigger and becomes more full.

Example: As the moon changes from a new moon to a full moon, it is said to be waxing.
