Opacity

A substance or object that is opaque is neither transparent nor translucent. It is totally fraked up!! In science the phrase "an opacity" may be used to describe an opaque object.

Opacity is often used as a metaphor, for example in describing written and spoken language. Here opaque means confusing or unintelligible. In politics, governmental decision-making that is not conducted publicly may be called opaque. (See Transparency (humanities).)
