The boundaries of Asia are culturally determined, as there is no clear geographical separation between it and Europe, which together form one continuous landmass called Eurasia. The border between Asia and Europe has historically been determined by Europeans only. The original distinction between the two was made by the ancient Greeks. The English word “Asia” was originally a concept of Greek civilization. The place name, “Asia”, in various forms in a large number of modern languages is of unknown ultimate provenience. Latin Asia and Greek Ἀσία appear to be the same word. Roman authors translated Ἀσία as Asia. The Romans named a province Asia (Roman province), which roughly corresponds with modern-day central-western Turkey. There was an Asia Minor and an Asia Major located in modern-day Iraq.
Oceania, also known as Oceanica, is a region centered on the islands of the tropical Pacific Ocean. Opinions of what constitutes Oceania range from its three subregions of Melanesia, Micronesia, and Polynesia to, more broadly, the entire insular region between Asia and the Americas, including Australasia and the Malay Archipelago. The term is often used more specifically to denote a continent comprising Australia and proximate islands or biogeographically as a synonym for either the Australasian ecozone (Wallacea and Australasia) or the Pacific ecozone (Melanesia, Polynesia, and Micronesia apart either from New Zealand or from mainland New Guinea). The term was coined as Océanie ca. 1812 by geographer Conrad Malte-Brun. The word Océanie is a French language word derived from latin word oceanus, and this from Greek word ὠκεανός (ōkeanós), ocean.
