What does coarsening mean?
Coarsening refers to the process by which something becomes coarse — that is, rougher in texture, cruder in quality, or less refined in character. It functions both as a noun naming this process and as the present participle of the verb "to coarsen." The word appears frequently in social and cultural commentary, where writers speak of the coarsening of public discourse, of manners, or of entertainment, always with disapproval: to describe something as coarsening is to suggest a decline from an earlier state of civility or polish. The term also has precise technical uses, most notably in materials science, where grain coarsening describes the growth of larger crystals within metals and alloys at high temperature. Whether applied to language, behavior, or microstructure, coarsening implies gradual degradation rather than sudden change, making it a useful word for describing slow erosion of standards or quality.
The process of becoming coarse, whether in physical texture or in manners, language, or general quality.
"The coarsening of the alloy's grain structure reduced its strength."
Frequent in cultural criticism and in technical writing about materials.
Present participle of "coarsen": making or becoming coarse.

The word 'coarse' likely traces back to the same roots as 'course' — so a 'coarsening' society is, oddly enough, drifting off its original course.

Etymology of coarsening
Coarsening derives from "coarsen," a verb formed from the adjective "coarse" plus the suffix "-en." The adjective "coarse" appeared in English in the late Middle Ages, originally as a variant spelling of "course," meaning ordinary or customary, before settling into its modern sense of rough or inferior in texture. As a noun form, "coarsening" follows the standard English pattern of turning verbs of change into nouns denoting their process.
