TermDecode is built for students and allied health learners who need to read medical words fluently. A term is broken into its prefix, root and suffix so the meaning can be worked out rather than memorised whole, and the study and quiz modes test recall. There is no account: progress, bookmarks, settings and quiz history stay in this browser's local storage.
Terms are filed under 10 categories, from anatomy and pathology through pharmacology to obstetric status. A word part page lists the terms in the library built from that part, and where a part carries more than one sense in medical terminology, each sense is listed separately.
Who runs it
One independent developer builds and publishes TermDecode, and also runs LabVals, DoseDrill and AnatoMemory, which cover lab values, dose calculation and anatomy. They are named here rather than linked, so the shared ownership is stated plainly.
Where the safety entries come from
High-risk abbreviation entries link the list they come from: the ISMP list of error-prone abbreviations, ECRI's notice of its 2024 update, or the Joint Commission do-not-use list. 81 of the 86 high-risk entries match a token on one of those lists and carry the “On ISMP list” tag; each of the rest carries a note explaining why it is kept.
Bylines and dates
The guides are published in TermDecode's name. None has an individual byline, no clinician or educator is named on the site, and the structured data behind every guide credits the TermDecode organization as author. Each guide shows when its text last changed.
Medical disclaimer
TermDecode is for education only. It is not medical advice, diagnosis, treatment guidance, or a substitute for clinical judgment, local policy, or instructor direction. It cannot tell you which abbreviations your hospital permits, and a definition here does not replace your course text or your institution's approved list.
