The word "bargain" can refer to a deal or agreement made between two parties where they negotiate terms, often related to the price of goods or services. It can also mean something that is bought for a price considered to be lower than its usual value, essentially a good deal. Additionally, "bargain" can refer to the act of negotiating the terms of a transaction.
The word "bargain" originates from the Middle English word "bargayne," derived from the Old French "bargaigner." It originally referred to the act of making a promise or an agreement and gradually evolved to its current meaning relating to negotiations in commerce.
