A troglodyte is a person who lives all alone, in seclusion. You could call this type a "hermit" or a "recluse," but it's more fun to say troglodyte.

Troglodyte is formed from the Greek words trogle, "hole", and dyein, "to dive into." The word translates to mean "he who dwells in caves." While a troglodyte can be what we think of as a pre-historic caveman, it also means someone who lives in any sort of tiny, unkempt house. Nowadays, a troglodyte generally refers to someone who lives alone, like a hermit. If you don’t mind having a dirty hole for a home, then perhaps you are a troglodyte.
