Reborrowing is the process where a word travels from one language to another and then back to the originating language in a different form or with a different meaning. This path is indicated by A → B → A, where A is the originating language, and can take many forms. A reborrowed word is sometimes called a ''Rückwanderer'' (German, a 'returner').
The result is generally a
doublet
Doublet is a word derived from the Latin ''duplus'', "twofold, twice as much",
