Pigeonhole refers to dividing or categorizing things in a strict manner. Some of the synonyms for pigeonhole include stereotype, compartmentalize, classify, label, and typecast. These words suggest the overgeneralization of ideas or people, and imply a rigid and inflexible approach to understanding different groups. Other synonyms could include categorize, organize, file, arrange, or sort. These words emphasize the orderly and systematic process of dividing information or objects into groups. They do not necessarily imply negative judgement or preconceived notions about the individuals or items being sorted.
