a mountain's hollow heart, carved by water too patient to ever quit
means A cavern is a large underground chamber or cave, usually one big enough to walk into.
from From Latin caverna, 'a hollow,' which traces back to cavus, 'hollow' — the same root that gives us 'cave' and 'cavity.' It reached English through Old French caverne. So at its core the word simply means an emptiness, a space defined entirely by what isn't there.
