What does corpuscule mean?
A corpuscule is a very small body or mass of matter. The word was especially used in early microscopy and historical physiology for tiny cellular structures observed in blood and connective tissue, with a blood corpuscule corresponding broadly to what would now usually be called a blood cell. Its sense could also extend more generally to any minute physical body or particle. Corpuscule is a recognized but uncommon spelling variant of corpuscle, and modern scientific and medical prose normally favors corpuscle or the more familiar cell. The term survives mainly in historical texts and specialized discussion, where it conveys the scale of an object that early observers could see only with a microscope. Its Latin-derived formation, a diminutive of corpus, “body,” also links it etymologically to a family of words concerning bodies, physical substance, and corpuscular matter.

- A small cell or cellular body, especially one formerly distinguished in blood or connective tissue.
"Under the microscope, each luminous corpuscule appeared to be a tiny, self-contained world."
"The early microscopist described the fluid as containing millions of minute corpuscules."
"A blood corpuscule was caught in the branching network of fine vessels."
The regular plural is corpuscules, though the word is now uncommon in contemporary prose.
"Tiny corpuscules moved through the liquid in an erratic swarm."
A corpuscule is to a cell roughly what a planet is to a star: an immense structure in miniature.

Where does corpuscule come from?
Corpuscule comes through French from Latin corpusculum, the diminutive of corpus, meaning “body.” The Latin form developed in the language of anatomy and natural philosophy before being borrowed into English for minute physical bodies, particularly cellular structures. Corpuscle and the less common corpuscule reflect parallel English forms from this same Latin source, while corpuscular continues the stem in an adjectival sense.
How corpuscule is actually used
The word is now rare and literary or historical. In modern scientific writing, corpuscle is generally preferred, and in biological contexts cell is normally the clearest term.
