### Zipf's law

(particular discrete probability distribution discovered in linguistics)

**Zipf's law** was formulated regarding word frequency in languages,
stating that the frequencies of a language's most common words are
proportioned 1 to 1/2 to 1/3 to 1/4 to 1/5 and so on. The notion
was explored by linguist George Kinsley Zipf, and such a probability
distribution is termed a **Zipfian distribution**. It has
been shown to approximate the distributions of words in multiple
languages and also other non-linguistic circumstances, and is a
candidate in characterizing the statistics of many kinds of sample
data under study. Sometimes the above idea is used with modifications,
expanding the pattern of proportions by inserting an added or
multiplied constant or a constant exponent. Also, analogous
continuous probability distributions are a possibility.
