Why are some terms not defined in USPAP?

Some terms are not defined in USPAP because they may have standard dictionary definitions that are sufficient for understanding within the context of appraisal practice. This approach allows for flexibility and consistency, as many common terms are widely recognized and understood in their general usage. By not redefining these terms within USPAP, the standards remain streamlined and accessible without unnecessary repetition. This helps appraisers avoid confusion while ensuring that they can rely on existing knowledge of these terms, which are often foundational to effective communication in the field. Furthermore, using standard definitions allows appraisers to connect USPAP guidelines with broader industry practices and terminologies that are familiar among professionals.
