Etymology: Trochidae is a zoological family name, and its history is a plain Latin-to-taxonomy pathway. The root is Greek "trochos", meaning wheel or hoop, which also gave English "trochee" and "trochlear". The shells of these snails are conical and spiral, so a name built on the idea of a wheel fits the coiled form well enough. The family name follows the standard zoological pattern: a genus name, "Trochus", is turned into a family name by adding the suffix "-idae", which marks animal families in Latin-based taxonomy. Naturalists coined the Latinised genus name from the Greek root, and the family name was then formed from it in the same way as thousands of other family names. The word was not in common English use before scientific classification, so it has no everyday history to trace. Its meaning has stayed fixed to the taxonomic group since it was introduced.
