coarser

Coarser is the comparative form of the adjective coarse. It describes something that is rougher in texture, less refined, or more crude than another item or state. The term is widely used across disciplines to indicate a larger scale, looser granularity, or more blunt characteristics.

In geology and materials science, coarser refers to larger grain or particle sizes. Coarse-grained rocks such as granite have visibly larger crystals, while fine-grained rocks like basalt have tiny crystals. In powders, sands, or filtering, a coarser grade implies bigger particles and a larger pore or sieve size.

In manufacturing and construction, coarseness describes grinding, finishing, or abrasion levels. A coarser abrasive removes material more quickly but yields a rougher surface, whereas a finer abrasive produces a smoother finish.

In textiles, coarser fabrics have thicker yarns or looser weaves, producing a rougher touch and greater bulk.

In language and communication, coarse language is vulgar or crude; coarser expressions are generally less restrained than milder forms and may be inappropriate in formal settings.

In computing and numerical analysis, a coarser mesh or grid has fewer elements and lower resolution, which can speed computations but reduce accuracy. The choice between coarse and fine representations depends on the required balance of efficiency and precision.
