Veterinary Terminology Cheat Sheet**Please note: This is not a full list of veterinary terminology. Students will be tested on a wider variety of terms.

Veterinary science, like any other field of medicine, has a vast amount of its own unique terms. Like other medical terminology, veterinary terms are best learned by breaking them down into their component parts. Veterinary terminology has three basic parts (not all of which are used in every word): the prefix, root, and suffix.
