Vocabulary Breadth
The number of distinct words a person knows at least superficially.
Why it matters
Breadth governs how much text a reader can follow. Below ~95% coverage of running words, reading becomes effortful and incidental learning stalls.
Examples
- A 10,000-word breadth covers most newspaper text; 20,000+ is typical for literate adults
Best practices
- Grow breadth via extensive reading of varied material
- Use frequency lists to confirm coverage as breadth grows
