introductory

Introductory is an adjective used to describe something that introduces or prepares for what follows. It denotes material or language that is preliminary, opening, or designed for beginners. The word is derived from the noun introduction, which comes from Latin introductio, from intrō "into" and ducere "to lead."

In education, an introductory course or class is intended for newcomers and covers basic concepts to build a foundation for more advanced study. An introductory chapter in a book or an introductory paragraph in an essay serves to present the topic, context, and structure before the main discussion.

Outside academics, introductory is used in marketing as introductory pricing or offers, which are temporary reduced prices to attract customers. In speech or writing, introductory remarks or phrases set the stage for what follows, and in grammar an introductory element precedes the main clause.

Overall, introductory materials are characterized by accessibility for new learners and by a role as a gateway to more complex material.
