I looked up the word
'recluse':
A recluse is someone in isolation who hides away from the attention of the public, a person who lives in solitude, i.e. seclusion from intercourse with the world. The word is from the Latin recludere, which means "shut up" or "sequester".
A person may become a recluse for many reasons: a celebrity may seek to escape the attentions of his or her fans; a misanthrope may be unable to tolerate human society; a survivalist may be practicing self-sufficiency; and a criminal might hide away from people to avoid detection by police. It can also be due to psychological reasons, like: apathy, an autism spectrum disorder, a phobia, schizoid personality type, or due to avoidant personality disorder. A recluse can also be considered as a loner.
