Did you know that the breastbone is also called the sternum?

Really? I had no idea it had another name!

Yeah, it's an important part of our rib cage.

Root Explanation

Breastbone → The word is formed from "breast" (from Old English *brēost*, meaning the front of the body) and "bone" (from Old English *ban*, meaning a hard structure that makes up the skeleton). The term "breastbone" refers to the bone located at the front of the chest, which is associated with the breast area.

Memory Tip

Think of the 'front of the body' ('breast') where the 'hard structure' ('bone') is located — that's why the breastbone is the bone at the front of your chest.
