A cup is a small container used to hold liquids for drinking, typically with a flattened hemispherical shape and an open "mouth", and often with a capacity of about 6–16 US fluid ounces (177–473 ml). Cups may be made of pottery (including porcelain), glass, metal, wood, stone, polystyrene, plastic, lacquerware, or other materials. Normally, a cup is brought in contact with the mouth for drinking, distinguishing it from other tableware and drinkware forms such as jugs; however, a straw and/or lid may also be used. They also often have handles, though many do not, including beakers which have no handle or stem, or small bowl shapes which are very common in Asia.
There are many specific terms for different types of cups in different cultures, many depending on the type of drink they are mostly used for, and the material they are made of; in particular, cups made of glass are mostly called a "glass" in contemporary English. Cups of different styles may be used for different types of liquids or other foodstuffs (e.g, teacups and measuring cups), in different situations (e.g, at water stations or in ceremonies and rituals), or for decoration.
