The term "least" refers to the smallest amount or degree of something. It is often used in comparisons to indicate the lowest level among a group. For example, if you have three numbers, 2, 5, and 8, the least number is 2. In everyday language, "least" can also describe preferences or choices. For instance, if someone says they like apples, bananas, and cherries, but they like cherries the least, it means cherries are their least favorite among the three options.
