Zipf's Law
In any natural language corpus, the most common word appears roughly twice as often as the second most common, three times as often as the third, and so on. This power law, known as Zipf's Law, holds remarkably consistently across languages and topics. Your top 10 words will typically account for 30-40% of all word occurrences.
