What percentage of English words are included in the established basic categories such as number words and color words?

The correct answer reflects a recognized estimate that roughly 20-25% of English words can be categorized as basic terms, which include foundational categories such as numbers and colors. Understanding this percentage is significant because these basic categories play a crucial role in language acquisition and literacy development.

Words in these fundamental categories are among the first learned by children and are frequently used in everyday communication. By focusing on such essential vocabulary, educators can effectively support students in building a solid foundation for further language development.

The other percentages provided in the choices reflect higher or lower estimates, which do not align with educational research on vocabulary acquisition patterns. This context emphasizes the importance of focusing on essential words that form the basis of language understanding and communication.
