A petty scholar, also known as a PEDANT, is someone who is overly concerned with details and rules. They are often seen as overly strict and rigid in their thinking, and they tend to focus on minor details rather than the bigger picture. Petty scholars are often seen as having an obsessive-compulsive attitude towards learning and knowledge. They are usually highly educated and knowledgeable, but their approach to learning can be seen as overly narrow and restrictive.
