A culture is a way of life of a group of people--the behaviors, beliefs, values, and symbols that they accept, generally without thinking about them, and that are passed along by communication and imitation from one generation to the next. Culture is symbolic communication.
When used as a count noun, a culture is the set of customs, traditions, and values of a society or community, such as an ethnic group or nation. In this sense, multiculturalism is a concept that values the peaceful coexistence and mutual respect between different cultures inhabiting the same territory. Sometimes culture is also used to describe specific practices within a subgroup of a society, a subculture (e.g. bro culture), or a counter culture.
