In this quote from Lewis Carroll's Alice in Wonderland, the character is attempting to imagine what the flame of a candle looks like after it has been extinguished. She has never experienced or seen a candle after it has been blown out, so her mind struggles to picture the extinguished flame accurately. This highlights her curiosity and the whimsical nature of her thoughts as she explores unfamiliar concepts.
The quote reflects a moment of innocent wonder and the playful perspective of a child, characteristic of Carroll's storytelling. Her inability to visualize the candle's flame post-blowout emphasizes the novelty of new experiences and the imaginative way children interpret the world around them, often imagining things beyond their direct experience.
