pellucidaan

Pellucidaan is a coined term used to describe the quality or state of pellucidity—transparency, clarity, or lucidity—in materials, media, and discourse. It functions as an abstract noun that can apply to physical surfaces that transmit light with minimal scattering as well as to written or spoken content deemed unusually clear.

Etymologically, the root pellucidus is Latin for clear or transparent; the suffix -aan is a noun-formation suffix used in several languages to indicate a property or quality. The term does not have a single authorial origin and has appeared sporadically in contemporary design and linguistic discussions as a neologism.

In design and architecture, pellucidaan is used to discuss materials such as glass or polymer that emphasize luminous transparency and color fidelity. In rhetoric and literary criticism, it denotes prose or argumentation that conveys meaning with exceptional directness, leaving little room for misinterpretation. Because it is a nonstandard neologism, its usage varies by author and context, and it may be unfamiliar to readers outside specific discourse communities. Some commentators contrast pellucidaan with obfuscated or opaque prose and with opaque materials that scatter light.
