Etymology

The word "capsule" traces back to Latin capsula, a diminutive of capsa ("box"). The original sense referred to a small container, which evolved to describe medicinal cases, spacecraft compartments, and biological membranes. The suffix -ule reinforces the idea of smallness, making "capsule" literally "a little box." Over time, its meaning expanded metaphorically (e.g., "capsule wardrobe" for a compact collection).
