What does denseness mean?
Denseness is the noun describing the quality of being dense — that is, packed tightly together, thick in substance, or difficult to pass through. It can characterize physical matter, as in the denseness of a hardwood block or a rich fruitcake, or things that obstruct light, movement, or visibility, such as fog, forest canopy, or an overcrowded city block. In figurative use, denseness also names a mental failing: a slowness to grasp ideas or take hints, as in 'his denseness exasperated everyone at the meeting.' This second sense is informal and disapproving. The word should be distinguished from density, which is generally preferred for precise, measurable quantities such as mass per unit volume or population per square mile; denseness tends to be the broader, more qualitative term. Derived from the adjective dense, which traces back to Latin densus meaning thick or crowded, denseness offers writers a useful way to convey both physical compactness and, with a touch of criticism, intellectual sluggishness.
The state or quality of being dense; thickness, compactness, or impenetrability, whether of physical material or, figuratively, of thought or understanding.
"The denseness of the smoke made it impossible to see across the room."
In scientific or technical contexts, density is usually preferred over denseness when a measurable quantity is meant.
Informal: slowness or dullness of comprehension; stupidity.
"She finally lost patience with his denseness and explained the plan twice more, slowly."
Rarely pluralized; as an abstract quality, denseness is almost always used as an uncountable mass noun.
"The essay compared the various densenesses of different wood species."
The same word that describes a rainforest so thick sunlight barely reaches the ground can also describe someone who just didn't get the joke.

Etymology of denseness
Denseness is formed by adding the native English suffix -ness to the adjective dense, which English borrowed in the 16th century from Latin densus, meaning thick, compact, or crowded. The suffix -ness is one of English's oldest word-forming elements, used since Old English to turn adjectives into abstract nouns denoting qualities or states. Cognates sharing the same Latin root include density, condense, and condensation, all of which entered English through Latin or its Romance descendants. The word has been in continuous use since the early modern period, developing both its literal physical sense and its figurative sense of dull-wittedness.
How denseness is actually used
Denseness is a somewhat formal or literary alternative to the more common and more technical density. When applied to people's intellect, it carries a clearly negative, often mildly insulting connotation and is best reserved for informal or critical contexts.
Easily confused with denseness
Density typically refers to a measurable quantity, such as mass per unit volume in physics or the number of items per unit area, while denseness more often describes the general qualitative quality of being thick, crowded, or hard to penetrate.
