Zipfian distribution

A Zipfian distribution is a pattern observed in many natural and social systems where a few items are extremely common, while most are rare. For example, a small number of words like "the" and "and" are used very frequently, while many words are used rarely. In this distribution, the frequency of an item is inversely proportional to its rank; the second most common item is about half as common as the most common, the third is a third as common, and so forth. This creates a predictable pattern that helps us understand how resources, words, or data follow a natural hierarchy.
