The word 'clock' is used to talk about a device that tells time. You can find a clock in many places, such as on the wall of a room, on your wrist as a watch, or in your phone. You might use a clock to plan your day, to make sure you're not late for school or work, or to time how long you spend doing something. Clocks can have a traditional look with hands that move around a face, or they can be digital with numbers that change on a screen. Regardless of the type of clock, it's a helpful tool for keeping track of time.
