Etymology

Origin of anatomy

First recorded in 1350–1400; Middle English, from Latin anatomia, from Greek anatom(ḗ) “dissection” (from ana- ana- + tomḗ “a cutting,” noun derivative of témnein “to cut”) + -ia -y ³

Explanation

If you're studying anatomy you're studying animals’ bodies and you're probably dissecting them, too. You might study the anatomy of a pig to see how it relates to human anatomy. You’ll find that only one of them has a snout. Ever heard of Gray's Anatomy — not the TV show, but the 1858 medical textbook by Henry Gray? It’s been revised many times, but it’s still the standard text, with detailed descriptions of the parts of the human body. The word anatomy can apply to anything you're analyzing in detail. If you're writing an anatomy of your piano, you'll describe the parts and how they work. Anatomy goes back to the Greek roots ana, meaning "up," and temnein "to cut."
