Global South
Etymology
Uses "South" loosely — many such countries do lie in the southern hemisphere, but the term is political and economic, not strictly geographic (Australia sits south yet counts as "North"). It rose to prominence to replace "Third World" and "developing world," which had grown dated or condescending.
noun phrase · /GLOH-bul SOWTH/
A grouping of countries, largely in Africa, Latin America, and Asia, positioned outside the wealthy Western power bloc.
What it names
It gives a current name to a shifting geopolitical bloc, replacing dated terms and signaling shared interests more than a location on the map.
Example
At the summit, leaders of the Global South pressed for a bigger voice in institutions built by wealthy nations.
Related idea
Successor to "Third World," a Cold War term for countries aligned with neither the capitalist West nor communist East; Global South reframes the grouping around wealth and power rather than superpower alignment.
