보다 (“to see” or “to try”) can be used to form an imperative -아/어 보다 in casual speech. This construction is used to suggest trying or attempting something.
For example:
이 책을 읽어 봐 → “Try reading this book.”
한번 해 봐 → “Try doing it once.”
조금만 더 다가와 봐 → “Come a little closer.”
This form softens the command, making it sound more like a suggestion or encouragement rather than a direct order
