“You can’t tell a book by it’s cover” is an old adage.

I guess the cover is wrong. am I right?

I disagree. A terrible book may have a beautiful cover.

“You can’t tell a book by it’s cover” is an old adage.

it's = ?
its = ?

Here is a thought for you:

What does that adage tell us about psychoanalysis?
Or buying a shiny used car?
Or trusting new friends?

One has to get to the deep content to know what it is. I am thinking of books that have impacted me: Of Mice and Men; Cannery Row; The winter of discontent.

tnx

The phrase "You can't judge a book by its cover" means that you shouldn't make assumptions about something or someone based solely on their outward appearance. In the context of your question, if you think the cover is wrong, it suggests that you are implying the content inside the book is different from what the cover indicates. To determine if your assumption is correct, you would need to read or explore the content of the book and compare it to the expectations set by the cover. By doing so, you can then assess whether the cover accurately represents the content or if it is misleading. So, the answer to your question depends on your investigation of the book's content compared to the expectations set by its cover.
