The term "law" refers to a system of rules created and enforced through social or governmental institutions to regulate behavior. Laws are designed to maintain order, protect rights and freedoms, and ensure justice within a society. They can be established by legislation, precedents set by courts (common law), or by other authorities.
The word "law" originates from Old English "lagu," meaning "something laid down or fixed." It has Germanic roots and is related to similar words in other languages, indicating the idea of rules or constraints.
