+[^1]: An [intent](luis-concept-intent.md) represents a task or action the user wants to perform. It is a purpose or goal expressed in a user's input, such as booking a flight, paying a bill, or finding a news article. In LUIS, the intent prediction is based on the entire utterance. Entities, by comparison, are pieces of an utterance.
+[^2]: [Entities](luis-concept-entity-types.md) are important words in [utterances](luis-concept-utterance.md) that describe information relevant to the [intent](luis-concept-intent.md), and sometimes they are essential to it. An entity is essentially a datatype in LUIS.
+[^3]: In the LUIS context, a **domain** is an area of knowledge. Your domain is specific to your app area of knowledge. This can be a general area such as the travel agent app. A travel agent app can also be specific to just the areas of information for your company such as specific geographical locations, languages, and services.
+[^4]: An utterance is a natural language phrase such as "book 2 tickets to Seattle next Tuesday". Example utterances are added to the intent.
