Sense: noun/1
Kangaroo, wallaby, and marsupial belong to related but distinct levels of meaning. A marsupial is any mammal that carries its young in a pouch — this group includes kangaroos, koalas, wombats, and Tasmanian devils. Within the marsupials, kangaroos and wallabies are both hopping macropods (meaning 'big-footed'), but kangaroos are the larger species, while wallabies are smaller. In Australia, people commonly distinguish them by size: a full-grown eastern grey kangaroo stands about as tall as a person, whereas a wallaby is much shorter. A joey is simply a baby kangaroo or wallaby. For example: 'We saw a huge red kangaroo bounding across the plain, and a little later a wallaby poked its head out of the bushes.'
Etymology
The word 'kangaroo' comes from the Guugu Yimidhirr language, spoken by Aboriginal people in northern Queensland, Australia. The original word 'gaŋurru' referred to a specific type of kangaroo. English speakers first wrote it down in 1770 during Captain Cook's voyage. Guugu Yimidhirr is still spoken by Aboriginal people in the Hopevale region of northern Queensland today.
