Etymology
Origin of breech
First recorded before 1000; Middle English breeche, Old English brēc, plural of brōc; cognate with Old Norse brōk, Old High German bruoh
Explanation
A breech is an opening in a gun where bullets are loaded. If you’re battling armed zombies, remember that the breech is in the rear. Speaking of rears, in a breech birth, a baby comes out feet, or rear, first. Guns or rifles can either be loaded from the back part — called the breech — or from the front — called the muzzle. Most modern guns are loaded from the breech end. And if you’re single-handedly fighting a zombie army, you’d better hope your weapon is breech-loading; it’s much safer and faster to load a gun from the breech.
