coarse-grained

The compound adjective "coarse-grained" is a relatively modern English formation, combining two words of distinct ancient lineages to create a descriptive term for physical and abstract qualities. The first element, "coarse," traces back to a Germanic root via Middle English, originally carrying a sense of ordinary or common quality, which evolved to denote a rough or harsh texture. The second element, "grain," originates from the Latin 'granum,' meaning a seed or small particle, which entered English through Old French and came to refer to the texture or arrangement of particles in a material like wood, stone, or sand. The suffix "-ed" is added to the noun "grain" to form an adjective, a productive pattern in English (e.g., "kind-hearted"). Literally meaning "having large or rough particles," the term's logic extends metaphorically to describe systems, analysis, or behavior that lacks fine detail and operates on a broad, general level, mirroring the physical property it first described.
