Mammatus is a noun used in meteorology to describe droplet-shaped, pouch-like cloud markings that hang underneath a cloud base, often forming a cellular or lobed pattern. The term also appears in anatomy to describe small, rounded projections on certain tissues, but in everyday meteorological discussion it refers to those pouch-like cloud features. The word denotes a specific, visually distinctive cloud formation and is primarily used in scientific or descriptive contexts.
