wallaby
Synonym discussion
Sense: noun/1
A wallaby is a small to medium-sized member of the macropod family, native to Australia and New Guinea. The word is most often contrasted with kangaroo, which refers to the larger species — red kangaroos can stand over 1.8 metres tall, while most wallabies grow only to about 60–90 centimetres. Pademelons are even smaller and stockier than wallabies, with shorter tails, and are found in dense forest areas. Marsupial is a much broader term: it covers any mammal that carries its young in a pouch, including koalas, wombats, and possums. If you see a large animal hopping across an open plain, call it a kangaroo; if it looks like a smaller version near a forest edge, wallaby is the right word; and if it is tiny, round-bodied, and scurrying through thick undergrowth, it is probably a pademelon.
Etymology
The word comes from the Dharug language spoken by Aboriginal people around Sydney, Australia. Early British settlers borrowed the term 'waliba' or 'walabi' in the late 1700s to describe the small kangaroo-like animals they encountered on the continent.
