The Best Tips for Learning Important Medical Words

Knowing medical terms just for the fun of it is fine. But some may be interested in or are already enrolled in a program where they need to know medical terms. If you want to pursue a career in healthcare in any capacity, you’ll want to study and fully understand medical terminology.

One key tip for learning medical terminology is dissecting the word to its roots, prefixes, and suffixes. These parts of the word will give away important information and clue you into what’s being discussed. For example, a term like bronchitis (inflammation of the airways) contains “bronch” which lets you know it’s about the airways. Another easy example would be carcinogenic (cancer-causing). Since it contains “carcin/o,” you know it has to do with cancer.
