Wax is a solid, slightly shiny substance made of fat or oil which is used to make candles and polish. It melts when it is heated.

If you wax a surface, you put a thin layer of wax onto it, especially in order to polish it.

If you have your legs waxed, you have the hair removed from your legs by having wax put on them and then pulled off quickly.

Wax is the sticky yellow substance found in your ears.

If you say that someone, for example, waxes lyrical or waxes indignant about a subject, you mean that they talk about it in an enthusiastic or indignant way.

If something waxes and wanes, it first increases and then decreases over a period of time.
