KK: /tɔːˈtɒnɪm/
A type of scientific name where the genus and species names are identical, often used in the classification of animals.
The scientific name for the western lowland gorilla is a tautonym: Gorilla gorilla.
Tautonym is formed from "tauto-" (from Greek "tautós", meaning the same) and "-onym" (from Greek "onuma", meaning name). The word refers to a name that is the same as another name, particularly in biological classification where the genus and species names are identical.
Think of 'the same' ('tauto-') when you hear 'tautonym', as it describes names that are identical.
