Formal meaning
Culture is a shared system of values, customs, beliefs, symbols, and practices that shapes how a group lives, communicates, and makes meaning. It includes visible elements (language, art, rituals) and invisible ones (assumptions, norms, worldview).
Etymology: Culture comes from Latin cultura (“cultivation, care”), from colere (“to cultivate, inhabit, nurture, worship”). The word later expanded from cultivating land to cultivating minds, communities, and ways of life.
