Etymology: "Granula" is the Latin word for a small grain, a diminutive of "granum," meaning grain or seed. The Latin diminutive suffix "-ula" marks it as "little grain," so the word simply describes something smaller than a grain. Its root "granum" is the same source behind English "grain" and "granary," the storehouse for grain. English borrowed the form directly from Latin, and it has been used as a technical term in scientific writing, where it names small particles or units. The core idea has stayed close to the original: a tiny, discrete piece of material, whether a grain of sand, a particle in a powder, or a small structure inside a cell.
