Recluse
Definition 1 of 1
Pro Tip 1/3
Voluntary Isolation
Recluse emphasizes a choice to avoid social contact, not just being alone by circumstance. She wasn't lonely; as a recluse, she chose solitude.
Pro Tip 2/3
Negative Undertone
The term can imply a judgment; suggesting someone is a recluse might seem critical. Calling him a recluse was unfair, even if he enjoyed solitude.
Pro Tip 3/3
Not Always Total
A recluse might still interact occasionally, just less often than most people. The village recluse would only come to town for essentials.
