cavern
UK: ˈkævən | US: ˈkævərn
n. a large cave or chamber in a cave, typically formed naturally
The word "cavern" originates from the Latin cavus (meaning "hollow"), which evolved into Old French caverne. The suffix "-ern" (from Latin -ernus) denotes a place or container, reinforcing the idea of a hollow space. The term has retained its core meaning of a large, naturally formed underground chamber, reflecting its etymological roots in the concept of emptiness or enclosure.
