nonclear

Nonclear is an adjective used to describe something that is not clear. It can refer to information or communication that lacks clarity, as well as physical properties that impede visibility. The term is formed from the negative prefix non- added to clear, and it is often used descriptively rather than as a fixed technical term.

In language and communication studies, nonclear language denotes wording that is ambiguous, vague, or unnecessarily complex. Factors contributing to nonclear language include lexical ambiguity, dense syntax, and insufficient context. Researchers measure readability and apply plain-language guidelines to reduce nonclarity and improve comprehension for diverse audiences.

In optics and materials science, nonclear refers to media or surfaces that do not transmit light clearly. Frosted glass, murky water, or cloudy plastics are described as nonclear, meaning they scatter or absorb light rather than producing a sharp, transparent image. The term is used descriptively alongside clear or transparent.

In everyday use, nonclear can describe instructions, policies, or displays that hinder understanding. While not a formal technical standard, it functions as a convenient shorthand for evaluating how well information can be interpreted by intended audiences.
