Culture can be defined as the knowledge, beliefs, arts, customs, and habits that are shared and learned by people in a society. It provides implicit instructions on what is right and wrong and shapes how people perceive and evaluate things. For a pattern of behavior or idea to be considered part of a culture, it must be shared with other individuals in that society. Cultures are dynamic and change over time in response to discoveries, inventions, and influence from other cultures through processes like diffusion and assimilation.
