Frequently Asked Questions
What is lexical density?
The percentage of content words — nouns, main verbs, adjectives and adverbs — out of all words in a text. The rest are function words: pronouns, prepositions, conjunctions, articles and auxiliaries.
What is a normal lexical density?
Spoken language usually sits near 30 to 40 percent, while written prose often reaches 50 percent or more. Very high density is not automatically better writing.
Does lexical density measure quality?
No. It measures how information-packed a text is, not whether it is clear, correct or well written. Use it alongside readability and your own judgment.
