American Heritage® Dictionary of the English Language, Fourth Edition
- n. A taxonomic designation, such as Gorilla gorilla, in which the genus and species names are the same, commonly used in zoology but no longer in botany.
Century Dictionary and Cyclopedia
- n. A name formed by repeating one word: as, kiwi-kiwi, the apteryx; taro-taro, the Orinoco bittern; awa-awa, the milk-fish of Hawaii; specifically, in zological and botanical nomenclature, a name in which the generic and specific names are the same: as, Scomber scomber, the mackerel; Cardinalis cardinalis, the cardinal redbird; Vulpes vulpes, the European red fox. These various animals were originally placed—mainly by Linnæus — each in a genus comprising species now regarded as belonging to different genera; in establishing new genera the old specific name was applied to the new genus and a new specific name given; this, by the rules of modem nomenclature, has been restored, the resulting name being a tautonym.
- n. biology, informal A binomial name consisting of the same word twice, such as Bison bison.
- taut- + -onym (Wiktionary)
