Entity types are user-defined traits or properties that are associated with an entity to identify the exact nature of the entity.
Impersonal awareness uses entity types to link entities that would otherwise not have a 1-degree relationship.
For example, if you wanted to find impersonal relationships using telephone calls, you would create a new entity type of Phone call and adjust your acquisition node to correctly tag each telephone call record with the Phone call entity type.
