Refers to something created by humans, opposed to nature. Culture can be used to describe the expressions of human creation, such as in "Norwegian culture", or about established practices in a group, such as "company culture". In general, culture can be tied to communication: culture is everything making it possible for humans to understand each other and interact, from language and ideas to ways of being and traditions. According to this interpretation, two people communicating will always share something cultural. This interpretation challenges ideas of cultures existing as something separate from each other.
