Etymology
The word 'cavern' originates from the Latin 'caverna', itself derived from the adjective 'cavus', meaning 'hollow'. This Latin root is traceable to the Proto-Indo-European base keuə-, signifying 'to swell' or 'to be vaulted', a concept that evolved to describe a hollow space. Entering English via Old French, the term has consistently denoted a large, naturally formed underground chamber. The modern spelling and meaning preserve this direct link to the ancient concept of a hollowed-out space within the earth.
