How can murkiness be best described?

Murkiness is best described as haziness because it conveys the idea of something being unclear, obscured, or difficult to see through. The term "murky" is often used to describe liquids, such as water, that are not transparent due to particles, sediment, or other impurities that make visibility poor. This aligns with the concept of haziness, where the environment or substance lacks clarity, creating a sense of uncertainty or indistinctness. In contrast, clarity denotes transparency and sharpness, brightness refers to the intensity of light, and simplicity describes an uncomplicated or straightforward quality. These alternatives do not encapsulate the essence of murkiness as effectively as haziness does.
