Which form does the word "least" indicate?

The word "least" is the superlative form of the adjective "little." Superlatives are used to indicate the highest degree of a quality among three or more items. In this context, "least" conveys the idea of the lowest amount or degree when comparing multiple entities or individuals.

For example, if you say "She has the least amount of experience," you are comparing her experience to that of several others, indicating that her experience is lower than the rest. This makes "least" distinctly a superlative according to the rules of English grammar.

Other forms like comparative or positive are relevant for indicating differences between two or more subjects or expressing an attribute without comparison, respectively, but in this case, "least" defines the superlative degree clearly and effectively.
