Etymology: The Greek word "ákari" meant "mite", the tiny creature so small that ancient writers had little to say about it beyond its size. Its name stayed in the Greek language for centuries, and the Latin "acarus" carried it into scholarly use, where it named the genus Acarus, the group of tiny creatures that later biologists gathered together. In the 19th century, taxonomists built the New Latin family name Acaridae from that genus name, and English borrowed the family label as "acarid" to refer to any member of it. The word is a straightforward piece of scientific coinage: a classical root, a family-making suffix, and a modern meaning that tracks the careful sorting of the natural world rather than any everyday speech.
