In Jim Trelease's "The Read-Aloud Handbook," he emphasizes that effective communication and understanding cannot be achieved without prior exposure to language through reading. The concept highlights the importance of reading as a foundational activity for developing vocabulary and forming coherent sentences. Reading provides the necessary input that allows individuals to articulate their thoughts clearly in writing or speech.

Treasuring the act of reading aloud, Trelease suggests that it enriches listeners' language capabilities and prepares them for better expression. This process of "uploading" knowledge into the mind is essential before one can "download" it onto paper, underscoring reading's critical role in learning and literacy development.
