If you're studying for the ITIL Foundation right now, here's something worth knowing before you crack open a single practice question: terminology went from 12% of the old exam to 30% in ITIL 5.0. That's not a small bump. It's the single biggest shift in how PeopleCert built this version of the exam, and it means memorizing vague definitions won't cut it anymore.
The ITIL v5 syllabus expects you to actually understand the language of modern service management, not just recognize a term when you see it. This glossary pulls together the 40 terms that show up most across the ITIL latest version syllabus, grouped so you're not just staring at an alphabetized wall of jargon.
Some of these carry straight over from earlier versions of the ITIL Framework. Others are brand new, built specifically for a world where AI governance and digital products sit at the center of the conversation.
Why Terminology Got This Much Weight in ITIL 5
The old ITIL Foundation exam tested you on the step-by-step mechanics of specific practices, incident management workflows, change control steps, that kind of thing. ITIL 5 dropped that entirely at the Foundation level. Instead, the exam checks whether you can speak the language fluently: do you know what an experience level agreement is versus a standard SLA? Can you tell the difference between agentic AI and general AI governance? That's the actual test now, and it's why this glossary matters more than any single practice diagram.

How to Study This ITIL Foundation Glossary Before Exam Day
Forty terms are quite a few for one person to try to remember at once, so don't try to learn them all in one session. Instead, organize them the same way this list has done, starting with the foundational concepts, moving through relationships and governance, and finally covering the more recent AI terminology. Then, test yourself on each group separately. Given that terminology accounts for 30% of the exam, this is the single most important thing you should learn before moving on to the Service Value System and the four dimensions.
For those who prefer learning with a certified trainer rather than working from a fixed glossary, Knowlathon has ITIL 5.0 Foundation courses tailored specifically to the new syllabus weightage. These courses can help you avoid having to redo what you have already learned through an older ITIL 4 course. Worth considering if you plan to take the exam in the coming months.
