Doppelganger

In fiction and folklore, a doppelganger or doppelga(e)nger (/ˈdɒpᵊlˌɡɛŋə/ or /-ˌɡæŋə/; German: [ˈdɔpəlˌɡɛŋɐ], literally "double-goer") is a look-alike or double of a living person, sometimes portrayed as a paranormal phenomenon, and is usually seen as a of bad luck. In other traditions and stories, they recognize one's 'double-goer' as an evil twin. Doppelgaenger is a German word which also means double walker.

The word 'doppelgänger' is often used in a more general sense to describe any person who physically or behaviorally resembles another person.

The word doppelgänger is a loanword from the German Doppelgänger, consisting of the two substantives Doppel (double) Gänger (walker or goer). The singular and plural forms are the same in German, but English usually prefers the plural "doppelgängers." It was first used by Jean Paul in the novel Siebenkäs (1796), and his newly coined word is explained by a footnote.
