What is the main function of a cup?

The primary function of a cup is to serve drinks. Cups are specifically designed and shaped to contain liquids, making them ideal for holding beverages such as water, coffee, tea, or juice. Their structure typically features a handle for easy gripping and a rim designed for drinking. This functionality is essential in the context of dining and serving, as cups provide a convenient way to enjoy various drinks.

While cups can hold food depending on their design, such as certain types of cups used for desserts or soups, their main purpose is still centered around serving liquids. Other options, such as cutting ingredients or storing food, relate to different kitchen tools and containers, which do not fall under the typical use of a cup.
