Metaphorical language is the use of a complex system of metaphors to create a sub-language within a common language which provides the basic terms (verbs, prepositions, conjunctions) to express metaphors. People who over-expose themselves to environments atypical from their usual habits tend to develop understanding of new words and apply new meanings to existing words. Such sources could include: absorbing a native language spoken in a different dialects or countries, a language other than their own and fictional language from books, music, films and videogames.
