50 Essential UX Terms Every Designer Should Know

If you’ve ever sat in a meeting and someone dropped “information architecture” or “cognitive load” like everyone should just know what that means — you’re not alone. UX terms can feel like a secret language, and honestly, a lot of people in the industry throw them around without fully understanding them either. This complete UX glossary breaks down 50 essential UX design terms with plain-English definitions and original infographic illustrations for each one. Think of it as your illustrated UX terms guide — whether you’re a beginner trying to get your bearings or a seasoned pro who needs a refresher, these are the UX terms that matter most. These definitions come from my book UX for Cats — a visual, fun, and slightly irreverent take on learning UX vocabulary. The book is designed for visual learners who want to actually remember what these terms mean, not just skim past them. Most of the content is right here on this page, but the print version is a much better reading experience (and way less scrolling). So grab your beverage of choice and let’s get into it. Here are the 50 most important UX design terms you need to know.
