How is "wispy" best described?

"Wispy" is best described as something that is thin and weak. The term generally refers to something that is delicate, lightweight, and often lacking in density, conveying an image of fragility. For instance, wispy clouds are often light and soft-looking in the sky, rather than being dense or imposing. This word evokes a sense of something that is fine and insubstantial, distinguishing it from other descriptions such as strong or vibrant, which suggest sturdiness or intensity. Therefore, identifying "wispy" as thin and weak captures its essence accurately.
