Etymology: Early microscopists peering at a drop of pond water saw crowds of moving specks and needed a name for them. They reached for a diminutive of "animal." The English term is a learned borrowing from Late Latin "animalculum," meaning a lowly or small animal, built from Latin "animal" plus the diminutive suffix "-culum." English then added its own diminutive ending, "-cule," so the Latin and English suffixes both shrink the idea. The Latin "animal" traces back to "anima," meaning breath, life, or soul, so a creature was first understood as something that breathes. Stacking a diminutive onto that gave a small living thing. The term was not limited to pond life. Human sperm, when first seen under the microscope, was also called animalcules. "Animalcules" is simply the plural of this noun.

Synonyms: microorganisms, microbes
