Etymology

Origin of bosom

before 1000; Middle English; Old English bōs ( u ) m; cognate with Dutch boesem, German Busen

Explanation

The bosom is the breast or chest area of the body. It is also poetically considered to be the place where our feelings reside. Used as a verb or noun, bosom originates from the Old English word bosm, meaning "breast, womb, surface, or ship's hold." It is commonly used as a polite reference to a woman's breasts. Because our bosom (chest) contains our heart, it has also become known as the place where our feelings, intuitions, or secret thoughts are kept. Close friends are sometimes called "bosom buddies."
