Etymology: The adjective "ciliate" was first recorded in 1760, borrowed from New Latin "ciliātus," a scientific coinage built on the Latin "cilium," meaning eyelid or eyelash. The "-ate" ending, which turns a noun into an adjective meaning "furnished with" something, did the rest: a "ciliate" organism is one fringed with hair-like structures. Those structures, called cilia, are the tiny beating hairs that some single-celled creatures use to swim and to sweep food toward their mouths. The Latin "cilium" traces back to the same eyelash sense, which explains why the word's root points to the eye rather than to anything microscopic. Naturalists of the eighteenth century borrowed the eyelash image for hairlike fringes on tiny organisms, a comparison that stuck because the fringes looked like rows of lashes along an edge.
