The phrase "will play" indicates a future action where someone or something is expected to engage in an activity, typically involving fun or recreation. It is often used in the context of sports, games, or performances, suggesting that a person or group will participate in an event at a later time. For example, if a child says, "I will play soccer," it means they plan to participate in a soccer game in the future. Similarly, a musician might say, "I will play a song," indicating their intention to perform a piece of music at a scheduled time.
