Step 1: Start from E. B. Tylor's classic definition:
Tylor (1871) defined culture as "that complex whole which includes knowledge, belief, art, morals, law, custom, and any other capabilities and habits acquired by man as a member of society".
Step 2: Explain the key word "learned":
Culture is not biologically inherited - it is acquired through socialization, which is why children raised in different societies develop very different cultural behaviours despite similar biology.
Final Answer:
Culture is society's learned and shared design for living, covering everything from beliefs and values to tools and customs, passed on through socialization.
