 From the etymological point of view, false friends can be created in several ways.If language A borrowed a word from language B, or both borrowed the word from a third language or inherited it from a common ancestor, and later the word shifted in meaning or acquired additional meanings in at least one of these languages, a native speaker of one language will face a false friend when learning the other.Sometimes, presumably both senses were present in the common ancestor language, but the cognate words got different restricted senses in Language A and Language B.
