The quote by Lewis Carroll suggests that when describing something like a shape, sound, or color, it's better to provide hints or subtle clues rather than stating it directly. This approach encourages imagination and deeper engagement from the listener or reader, allowing them to interpret and discover the subject on their own. It emphasizes the value of suggestion and nuance in communication, urging us to hint at details instead of overtly explaining them. By doing so, we make the act of understanding more intriguing and interactive, inviting others to use their creativity to fill in the gaps.

"When you are describing, A shape, or sound, or tint; Don't state the matter plainly, But put it in a hint"
