# Taxonomy and Vocabulary {% embed url="" %} ## Definitions A **taxonomy** in Drupal (and GovCMS) is a way to classify or categorise certain types of *content*. A **vocabulary** is a **group** of *taxonomy* terms. A *vocabulary* can only be used to categorise one type of *content*. For example, only the *Event categories* *vocabulary* can be used to categorise content of type *Event*. These terms and the distinction between them is best illustrated by an example. Page articles can be classified or categorised by the **Topics** they relate to. The categories or *taxonomy* terms can be Policies, News or Services. The *vocabulary* in this example would be called **Topics**. ## View vocabularies and taxonomy terms To see the list of *vocabularies* available to use on a site, hover over *Structure* on the *Admin menu* then click **Taxonomy**.

Click on the **List terms** to the right hand side any of the *vocabularies* listed to show the list of *taxonomy* terms it contains. In the screenshot below, the Topics terms are shown.

## Add a taxonomy term to content When creating (or editing) *content* of type *Page* content, authors can add a Topic (*taxonomy* term) to the content. Only the **Topics** vocabulary can be used for the *Page* content type (unless your developers have configured additional vocabularies).
