What does cavernous mean?
"Cavernous" is an adjective describing something vast, hollow, and suggestive of a great underground cave — a cavernous hall, warehouse, or stadium is enormous and largely empty, its dimensions emphasized by echoes and shadow. By extension it can describe sounds: a cavernous voice or laugh is deep and resonant. The word also has an important technical life in medicine, where "cavernous" refers to tissue riddled with small cavities, as in a cavernous hemangioma or the cavernous sinus of the skull. Derived from Latin caverna ("cave") via the English noun cavern, it entered English around the early seventeenth century. Its connotations range from awe at monumental scale — architects and critics use it admiringly of grand interiors — to slight bleakness when describing impersonal spaces. It is a precise, vivid choice whenever hollowness and immensity matter more than mere size, distinguishing a cavernous room from one that is simply large.

- Vast and hollow like a cavern; having a large empty interior, especially one that echoes (e.g. a cavernous hall, a cavernous laugh).

"The sound echoed through the cavernous hall."
"The orchestra rehearsed in the cavernous auditorium, where every note seemed to linger for seconds."
"The MRI revealed a small cavernous malformation near the patient's brainstem."
Doctors use 'cavernous' to describe blood vessels so full of hollow spaces they look like tiny sponges — the same word you'd use for a cathedral's echoing nave.

Etymology of cavernous
Cavernous derives from Latin caverna, meaning "cave" or "hollow," itself from cavus, "hollow," the same root that gives us cavity and excavate. The word entered English in the early seventeenth century via the established noun cavern, taking the adjectival suffix -ous. Cognates sharing the Latin root include concave and excavation.

How cavernous is actually used
The literal architectural sense is neutral to slightly formal; describing a voice or laugh as cavernous emphasizes depth and resonance rather than size. In medical contexts, 'cavernous' has a precise technical meaning relating to spongy, cavity-filled structures (as in the cavernous sinus or erectile tissue), and should not be read figuratively there.
