Teacup

A teacup is a porcelain cup that is used to hold liquid for drinking. It is usually used for drinking tea. It is also used for drinking coffee or some other hot drink. A teacup has a handle on the side that stays cool when the rest of the cup is too hot to hold. It also has its own small plate to sit on, called a "saucer".
These can be made from ceramic, clay, glass or even plastic. Usually, teacups are ceramic (made of porcelain) because it is safer. Teacups can also be made for decoration. If they are made for decoration, their owners might keep them on display and not actually use them. 
Teacups are often decorated with patterns or pictures. Those painted by hand can be expensive. Some people collect decorated teacups as a hobby.
