Etymology: Latin "particula" is a diminutive of "pars", "part", so it literally means "little part" or "small portion." The diminutive ending "-cula" gives the sense of smallness, the same pattern found in words like "homunculus" (little man). In Latin, it was used for a small piece of something, and English took the word over with that sense intact, using it for a tiny speck of matter. The word came into English as a borrowing directly from Latin, and its use in English is largely scientific and philosophical, where it describes a minute bit of material. Over time, the term also found its way into physics, where "particle" became the general word for the smallest units of matter, a sense that has grown far beyond its original Latin meaning of a simple small part.
