Etymology: Togaviridae is a taxonomic name, and its story is mostly one of naming conventions. The family name follows the pattern used for virus families, with the suffix "-viridae" marking a family rank, and the stem "toga" comes from the Latin "toga," the loose garment worn by Roman citizens. The name refers to the envelope that wraps the virus particle, which was seen under the microscope as a cloak-like outer layer around the core. The word was formed in the modern era, when virologists began grouping viruses into families according to shared structural and genetic features. It is a technical coinage built from classical material, not a term that the ancient Romans or Greeks ever used for viruses. The "toga" element is a metaphor, chosen because the outer coat of these particles resembled a garment draped over the core.

Synonyms: Togavirus family, Togaviruses
