What does obscuration mean?
Obscuration is a formal noun meaning the act of hiding something or the condition of being hidden, covered, or made difficult to perceive. Its uses range from physical descriptions, such as clouds obscuring the sun, to criticism of deliberate concealment in politics, business, and investigations. When it refers to language or information, it often carries the implication that the concealment is intentional and intended to prevent understanding. The word is less common than the simpler concealment or hiding, but it can give a more precise or elevated tone to formal and analytical writing. It is also used in technical contexts, including astronomy and visibility, where an object’s light becomes blocked or less visible. The related noun obscurity most often describes the quality of being unclear or little known, whereas obscuration highlights the process that produces that result.

Where does obscuration come from?
Obscuration was formed in the early 17th century from the Latin-derived word obscure and the suffix -ation. Obscure comes through Old French from Latin obscurus, meaning dark or hidden and formed from the prefix ob-, meaning over or upon, and a root associated with concealment. The same Latin root also underlies opaque, which originally referred to darkness and later came to mean difficult to see through or understand.
