Vocabulary size varies widely among individuals.

Vocabulary size can vary significantly from person to person. Some estimates suggest that the average adult native English speaker has a vocabulary size of around 20,000 to 35,000 words, while highly educated individuals may have a much larger vocabulary of 50,000 words or more. Factors like education, exposure to language, reading habits, and personal interests can all influence the size of an individual's vocabulary. Additionally, different languages have different numbers of words, with some languages having larger or smaller vocabularies compared to others.
