# Semantic Tag

<mark style="color:$danger;">**This Editorial Guide is used for Education Purposes Only. It is used in the Authoring Courses and Certifications. It is based on the January 2026 Editorial Guide.**</mark>

A s*emantic tag* is part of a concept's Fully Specified Name description. It is placed in parentheses at the end of an FSN when authoring concepts. It indicates the domain to which a concept belongs; for example: body structure, disorder, or specimen.

The purpose of semantic tags is to disambiguate concepts which have the same commonly used word or phrase.

* For example,
  * Hematoma (morphologic abnormality)
    * Hematoma (disorder)

The following table contains the semantic tags for each domain.
