Etymology: Osmeriformes is a taxonomic name, and its story is a matter of Latin and Greek building blocks rather than a single memorable coinage. The core is "Osmerus," the genus name for the smelts, which was itself taken from the Greek "osmē," meaning "smell" or "scent." Smelts are named for the cucumber-like odour of their flesh, and the scientific name records that same sensory note. The ending "-iformes" is a standard zoological suffix, from Latin "forma" meaning "shape" or "form," used to name an order, so the whole word means roughly "smelt-like" or "of the form of Osmerus." The name is a modern scientific coinage, formed under the rules of the International Code of Zoological Nomenclature, which governs the naming of animal groups. Order names of this type were standardised in the nineteenth and twentieth centuries, so the word was never used by the ancient Greeks, even though its parts come from their language.
