Normatively, the phrase may describe the effort to suit one's rhetoric to the widest possible audience, without losing relevant information in the process.
Advocates of normative linguistic transparency often argue that linguistic opacity is dangerous to a democracy. These critics point out that jargon is deliberately employed in government and business. It encrypts morally suspect information in order to dull reaction to it: for example, the phrase "collateral damage" to refer to the manslaughter of innocents.

Writer and political philosopher George Orwell was a proponent of this view, which he captured in the landmark essay, "Politics and the English Language." Orwell wrote a novel, 1984, about a dystopian future controlled through a politically crafted language called "Newspeak." Newspeak is a language that is linguistically transparent in the descriptive sense, but not in the normative one.

The approach may sound like common sense, but it faces the difficulty of figuring out how to communicate complex and uncommon ideas in a popular way.
Semantic transparency is a descriptive phrase that has been used in linguistics to describe endocentric compounds. Endocentric compound words are those whose whole meaning can be figured out by an analysis of its parts or "morphemes". An example of an endocentric compound is the word "car-wash". By contrast, some compound words are exocentric, meaning their whole meaning cannot be established by an analysis of parts; for example, the word "hogwash". Exocentric words are also known as semantically opaque.
