nænnin

Nänni is a Finnish noun that commonly means nipple or teat. The word nännin is the genitive singular form, used to indicate possession, as in nännin väri (the color of the nipple) or nännin hoito (care of the nipple).

In human anatomy, nipples are protrusions located on the chest or breast and are part of the breast's lactation system. They surround the areola and contain ducts that transport milk from mammary glands to the infant during breastfeeding. Nipples are composed of skin, connective tissue, and nerve endings, which provide sensitivity. They can become erect in response to temperature, touch, or other stimuli. The appearance of nipples and areolae varies widely among individuals in terms of size, color, and shape.

In other mammals, teats or nipples serve as the external openings of the mammary glands. The number and arrangement of teats vary by species and are a key feature in dairy farming and animal care. Teats are cultivated and managed to promote lactation, health, and milk production. In some animals, teats may be located along the abdomen or chest, and their condition can be an indicator of overall health.

Linguistically, nänni is used in Finnish to refer to the anatomical feature, and nännin is used when describing possession or characteristics of a nipple. The term appears in medical, educational, and everyday Finnish language, and is part of broader discussions of anatomy and lactation.
