The idiom "don’t judge a book by its cover" means that you should not judge someone or something based solely on their appearance. It means that you should not make assumptions about a person or thing based on how they look or seem on the surface.
For example, if you meet someone who looks unkempt or disheveled, you should not assume that they are lazy or uneducated. They may be going through a difficult time or have other reasons for their appearance. Similarly, if you see a book with a plain or unattractive cover, you should not assume that the book is not interesting or informative. It may have valuable information or be a great read despite its appearance.
This idiom is used to remind people that appearances can be deceiving and that it is important to look beyond the surface to truly understand someone or something. It encourages people to be open-minded and to give others a chance before making judgments based on superficial factors.
