The word "sky" refers to the space above our heads where we can see clouds, stars, the moon, and the sun. It is used when talking about the weather or looking upward to see what is happening in the atmosphere. For example, you might say "the sky is blue" on a sunny day, or "the sky is cloudy" when it is overcast. It can also be used to describe the time of day, such as "the sky is getting dark" when the sun sets. The word is typically used in casual conversation and in written communication.
