In the Shona language, zimbabwe translates approximately to "stone house", and because of the site's size and scope, it became known as Great Zimbabwe. Moreover, it was not the only such "Zimbabwe": there are remains of approximately 200 smaller settlements or trading posts spread across the region, from the Kalahari Desert in Namibia to Mozambique. 

According to Munyaradzi Manyanga, a professor of archaeology and cultural heritage at Great Zimbabwe University, the position of Great Zimbabwe among these settlements has been widely debated. Some people have speculated that it was a capital city of a very large state, but to Manyanga, that seems unlikely. "Such a state would have been too large. One wouldn't have been able to manage that kind of extent and size. So most of the interpretations talk of these as having been influenced by Great Zimbabwe." He added that the Kingdom of Zimbabwe is considered to be made up of Great Zimbabwe and the smaller settlements located closer to it.
