What does coarseness mean?
Coarseness is a noun describing the quality of being coarse, with two principal senses. In its physical sense, it refers to roughness or lack of fineness in texture — the gritty feel of sandpaper, the loose weave of sackcloth, or the thick grain of unpolished timber. In its social and moral sense, it denotes vulgarity, crudeness, or indelicacy in language, behaviour, manners, or taste: a joke told too loudly, a remark lacking tact, or conduct that offends refined sensibilities. The word derives from "coarse", which itself traces back through French to Latin "cursus", meaning a course or run — originally referring to ordinary, everyday cloth as opposed to finer fabrics. Because the social sense carries an implicit standard of refinement, using it often signals disapproval, making it a word of judgement as much as description. It remains useful both in technical contexts, such as textiles and materials science, and in literary or everyday criticism of style and manners.
nounThe quality or state of being coarse; roughness of texture, or vulgarity and crudeness of manner, language, or taste.

"The coarseness of the fabric made it unsuitable for fine clothing."
"The coarseness of the sandpaper left deep scratches in the wood."
"She was taken aback by the coarseness of his remarks at the dinner table."
Rarely used; the plural appears mainly in contexts discussing multiple distinct instances or varieties of coarseness, such as literary criticism.
"The essay catalogued the various coarsenesses of eighteenth-century satire."
"Coarseness" carries a double life: it can describe both the scratchy texture of burlap and the cringe-worthy crudeness of a joke — one word bridging touch and taste.

Etymology of coarseness
Coarseness is formed from the adjective "coarse" plus the noun-forming suffix "-ness". "Coarse" appeared in English in the late Middle Ages (attested from around the early 15th century), probably as a variant of "course", deriving via Old French "cours" from Latin "cursus", meaning "a running, course". It originally described ordinary or common-quality goods — especially cloth of everyday rather than fine quality — before extending to texture generally and then to figurative senses of vulgarity and crudity. The abstract noun "coarseness" developed naturally once the adjective was established.

How coarseness is actually used
The word spans both physical description (texture, grain) and moral or social judgement (behaviour, speech). When applied to people or their conduct it is inherently negative and somewhat formal in register; when applied to materials it is neutral and technical. Context usually makes clear which sense is intended.
