Definitions

Etymology: "Outpouchings" is the plural of "outpouching," a noun formed from the verb "pouch" with the prefix "out-". To pouch means to form a pouch, or to bag out like a sack, and the prefix "out-" adds the sense of extending outward from a surface. An outpouching is therefore a part that bulges or sticks out from its surrounding structure. The word is a plain compound of English elements rather than a borrowing, so its history is short and transparent. "Pouch" itself comes from a Germanic root related to the idea of a bag, and "out-" is a native English prefix used in countless words such as "outgrowth" and "outcrop." Combining them produced a technical-sounding term suited to describing bulges in anatomy, biology, and engineering.
