Etymology of Taxon Names
The information below provides a list containing descriptions of the origins of ICTV taxon names starting at the rank of realm and going down to the rank of family. This information is derived from the proposals that were submitted when each taxon was created. Links to these proposals, links to ICTV report chapters, and links to publications (through PMIDs) are provided when available.
We thank Stuart Siddell for compiling this list of name origins. Etymological information for taxa below the rank of family, can be found in the relevant ICTV Online (10th) Report chapters. If you have any comments or corrections, please contact us by sending an email to info@ictv.global.
Please select the virus realm containing your taxa of interest:
Realm: Unassigned

from the host genus name Bartonella and gene transfer agent; the suffix -viriformidae is used for viriform family taxa
from the Latin bi meaning "two" and the Latin cauda meaning " tail", referring to the virion morhologlogy of viruses in the family; the suffix ‑viridae for family taxa
from the host genus name Brachyspira and gene transfer agent; the suffix -viriformidae is used for viriform family taxa
from Latin clava, meaning "club" or "stick", referring to the rigid, bacilliform virion morphology of viruses in the family; the suffix ‑viridae for family taxa
from the Latin fusillo, meaning "little spindle", referring to the virion morphology of viruses in the family; the suffix ‑viridae for family taxa
from the Latin globulus, meaning “small ball”, referring to the virion morphology of viruses in the family; the suffix ‑viridae for family taxa
from the Latin gutta, meaning "drop", referring to the droplet-shaped virion morphology of viruses in the family; the suffix ‑viridae for family taxa
from halophilic, referring to the halophilic archaeal hosts of viruses in the family and spindle-shaped, referring to virion morphology of viruses in the family; the suffix ‑viridae for family taxa
from Itzamna, lord of the heavens as well as night and day in the Mayan mythology; the suffix ‑viridae for family taxa; connection unclear
from the Latin ovalis, meaning "egg shaped", referring to the exceptional virion capsid architechture of viruses in the family; the suffix ‑viridae for family taxa

from the Ancient Greek πολύς (polús), meaning “many" and DNA for deoxyribonucleic acid, referring to the multiple segments of dsDNA genomes of agents in the family; the suffix -viriformidae is used for viriform family taxa
from the Latin portare, meaning ‘to carry’ and globus, meaning ‘a ball’, referring to the round shape of the nucleoprotein virion core of viruses in the family; the suffix ‑viridae for family taxa
from potato spindle tuber viroid, a member of the family; the suffix -viroidae for viroid family taxa is used for these infectious agents, consisting only of naked RNA ; the suffix ‑viridae for family taxa
from the host order name Rhodobacterales and gene transfer agent; the suffix -viriformidae is used for viriform family taxa
from the Latin spira, meaning “coil”, referring to virion morphology of viruses in the family; the suffix ‑viridae for family taxa
from thaumarchaeal and spindle-shaped virus, referring to the host and virion morphology of viruses in the family; the suffix ‑viridae for family taxa
from tomato leaf curl virus satellite, the first DNA satellite shown to be associated with geminiviruses and the Latin satellit, meaning "attendent", for families that are dependent upon a helper virus to spread. The suffix -satelittidae is used for satelitte family taxa
