Nipple → The word originates from Old English 'nippla', which is a diminutive form of 'nippan' (meaning to nip or pinch). It refers to a small projection or protuberance, particularly in the context of the human body.
Think of a small 'pinch' ('nip') that creates a 'projection' — that's why a nipple is a small projection on the body.
