 ## Create entities for the app
 
-While entities are not required, they are found in most apps. The entity extracts information from the user utterance, necessary to fullfil the user's intention. There are several types of [prebuilt](/dotnet/api/microsoft.azure.cognitiveservices.language.luis.authoring.modelextensions.addprebuiltasync) and custom entities, each with their own data transformation object (DTO) models.  Common prebuilt entities to add to your app include [number](../luis-reference-prebuilt-number.md), [datetimeV2](../luis-reference-prebuilt-datetimev2.md), [geographyV2](../luis-reference-prebuilt-geographyv2.md), [ordinal](../luis-reference-prebuilt-ordinal.md).

 It is important to know that entities are not marked with an intent. They can and usually do apply to many intents. Only the example user utterances are marked for a specific, single intent.
