The word 'unseen' means something that is not visible or not noticed by anyone. It can be used to describe things or situations that people are not aware of, such as a hidden object or a secret activity. For example, you might say "the thief entered the house through an unseen window" or "the bird flew away unnoticed and was unseen by anyone." It is important to note that 'unseen' is often used in a formal or academic context, such as in written essays or exams.
