A drinking cup, also referred to as a mug, tumbler, glass, or beaker, is a container used for holding and consuming liquids such as water, juice, tea, coffee, and more. Other synonyms for a drinking cup include goblet, stein, chalice, tankard, pitcher, bottle, flask, and thermos. These words may refer to specific types or shapes of vessels, such as a goblet with a stem or a thermos with a lid, but ultimately all serve the same basic purpose of holding liquid for consumption. The choice of synonym may depend on personal preference, cultural traditions, or the type of beverage being consumed.
