Editing Capybara (section)

==Etymology==
Its common name is derived from [[Tupi language|Tupi]] {{lang|tpn|ka'apiûara}}, a complex agglutination of {{lang|tpn|kaá}} (leaf) + {{lang|tpn|píi}} (slender) + {{lang|tpn|ú}} (eat) + {{lang|tpn|ara}} (a suffix for agent nouns), meaning "one who eats slender leaves", or "grass-eater".<ref>Ferreira, A. B. H. (1986) ''[[Novo Dicionário da Língua Portuguesa]]'', 2nd ed., Rio de Janeiro: Nova Fronteira, p.344</ref> The [[genus name]], ''hydrochoerus'', comes from [[Ancient Greek|Greek]] {{lang|grc|ὕδωρ}} (''{{lang|grc-Latn|hýdor}}'' "water") and {{lang|grc|χοῖρος}} (''{{lang|grc-Latn|choíros}}'' "pig, hog") and the species name, ''hydrochaeris'', comes from Greek {{lang|grc|ὕδωρ}} (''{{lang|grc-Latn|hýdor}}'' "water") and {{lang|grc|χαίρω}} (''{{lang|grc-Latn|chairo}}'' "feel happy, enjoy").<ref name=msw3>{{MSW3 Woods|id=13400218|page=1556}}</ref><ref name="inDarwin">{{Cite book | last=Darwin | first=Charles R. | author-link =Charles Darwin| year=1839 | title=Narrative of the surveying voyages of His Majesty's Ships Adventure and Beagle between the years 1826 and 1836, describing their examination of the southern shores of South America, and the Beagle's circumnavigation of the globe.
