Etymology: "Saccules" is the plural of "saccule," a small sac or pouch in the body, such as the sacs of the inner ear. The singular comes from Latin "sacculus," meaning "a little sack or bag," a diminutive of "saccus," the ordinary word for a bag or sack. Borrowing the Latin form directly, English kept the sense of something small and bag-like, which is exactly how anatomists describe these tiny structures. Since "sacculus" and "saccule" share a Latin source, they are doublets: the same word that arrived in English in two forms. The shared root "saccus" also lies behind the English "sack," which came through a different route, showing how one Latin noun for a bag reached the language twice.

Synonyms: pouches, vesicles, bladders, cavities, sacs
