A cave-dweller; a caveman; one who lives in a naturally formed cavity in the rocks, or, by extension, one who has his abode in a dwelling-place of that kind, whether constructed by enlarging a natural cave or by making an entirely new excavation.n. Hence, one living in seclusion; one unacquainted with the affairs of the world.n. In mammalogy, an anthropoid ape of the genus Troglodytes, as the chimpanzee or the gorilla, especially the former, which was earlier known to naturalists and was called Simia troglodytes.n.
