"کم" (Less) refers to a smaller quantity or degree of something. It is often used in comparisons to indicate a reduction or a smaller amount in relation to another item. For example, if you have two apples and you give away one apple, you now have less than you started with. In everyday language, "کم" can describe various contexts, such as less time, less money, or less effort. It helps convey the idea of scarcity or a decrease in something, making it a useful term in both casual conversation and formal discussions.
