Scyphus is a fairly uncommon word that refers to a drinking vessel, typically a cup or goblet with a shallow bowl and a stem. While it may not be a term that many people use in everyday conversation, it does have a number of synonyms that can be used to describe similar objects. For example, a scyphus could also be called a chalice, a tumbler, a chalice, a goblet, or a cup. Each of these words has slightly different connotations and historical associations, so the choice of word may depend on the context in which it is used. Nevertheless, all of these terms can be used to describe a type of drinking vessel that has been used for centuries across various cultures.
