The drink that's made by soaking dried leaves in very hot water is called tea. On a hot summer day, many people like to drink iced tea.
Use the word tea for the drink you sip in a cup and also for the dried leaves used to make it. Aside from water, tea is the most common beverage in the world, and it's been around since at least the 28th century BCE, when historians believe it was invented in China. In Britain, tea is also a meal, typically eaten in the middle of the afternoon. Before the 18th century, the word tea was pronounced "tay."
