If you've spent more than a few hours researching teen treatment, you've encountered an entire dialect — clinical, regulatory, insurance, and industry jargon, often used in ways that obscure rather than clarify.
This glossary is a working reference. Each term is defined plainly, with notes on how the term is used, where it can be misleading, and which articles in Hartley cover it in depth. The glossary is being built in alphabetical order; entries marked "coming soon" are scheduled for clinical review before publication.
