Etymology: "Acarine" is built from "acar-", the combining form of the Greek "akari", meaning a mite or tick, plus the suffix "-ine", which English uses to form adjectives and nouns relating to something. The root "akari" is linked to the Greek "akairos", meaning "unseasonable" or "at the wrong time", a reference to the tiny size of these creatures, though that connection is not firmly established. The word belongs to the same family as "acarid", which covers the mites and ticks, and the two terms overlap closely in use. The exact date of the first coinage is not something the available record pins down, so the word's precise entry into English remains uncertain. What is clear is that its shape is a straightforward scientific construction: a classical root with a modern English ending, assembled to name a group of arachnids rather than inherited from ancient usage.
