What is a minor premise?

A minor premise is one of the two premises in a syllogism. It presents a specific example of the belief that is stated in the major premise. The minor premise is the second statement in syllogism and contains the subject of the conclusion.

For example, in the syllogism “All books in that bookstore are second-hand. This book is from that store. Therefore, this book is second-hand”, the minor premise is “This book is from that store”.
