South is one of the four cardinal directions. These are the primary compass points used for navigation. South is the direct opposite of north. It is also perpendicular to east and west. In many systems, south is abbreviated as S.

Most people follow the convention of placing south at the bottom of a map. However, some maps do not follow this rule. An example is the 1943 drawing "América Invertida" by Joaquín Torres García.

Language tells us how ancient people understood this direction. The word south comes from the Old English word "sūþ." This likely relates to a Proto-Germanic root. Some languages define south by the position of the sun. For example, the Latin word "meridies" means both noon and south. This comes from words meaning "middle" and "day." Other languages use the rising sun as a reference point. Biblical Hebrew and Aramaic describe south as the right-hand side of the rising sun. The name of the country Yemen comes from this idea. It refers to the land to the south or right of the Levant.

Navigators use specific tools and signs to find south. A compass can be set to a bearing of 180 degrees. This is known as an azimuth. In the Northern Hemisphere, you can also use the sun. Outside of the tropics, the sun is roughly in the south at midday. There are also two different types of south poles. The South Pole is the end of the axis for Earth's rotation. This geographic pole is located in Antarctica. Magnetic south is a different direction. It points toward the south magnetic pole, which is some distance away from the geographic pole.

Exploring the South Pole was a major historical event. Roald Amundsen was the first person to reach the geographic South Pole. He was from Norway and arrived on 14 December 1911. Another explorer, Ernest Shackleton from the UK, also attempted the journey. However, Shackleton was forced to turn back some distance before reaching the pole. These expeditions helped humans understand the geography of the Antarctic continent.

Today, the term "Global South" describes a specific social and economic reality. It refers to the less-developed southern half of the globe. There are large differences between the Global North and the Global South. In the Global North, 95% of people have enough food and shelter. They also have functioning education systems. In the Global South, only 5% of the population has enough food and shelter. These regions may lack appropriate technology or political stability. Their economies often depend on exporting primary products.

People also use "south" to name specific regions or countries. South Africa is named for its location at the southern tip of Africa. It was originally called the Union of South Africa. This name reflected the unification of four British colonies. Australia comes from the Latin name "Terra Australis," which means "Southern Land." In South America, the Southern Cone is a large area. It is shaped like an inverted cone or a large peninsula. This region includes Argentina, Chile, Paraguay, Uruguay, and the southern parts of Brazil. Some definitions of the Southern Cone are more restricted. They may only include Chile, Argentina, and Uruguay.

Even within single countries, the term can mark a divide. The Southern United States is separated from the Northeast by the Mason–Dixon line. In England, the South is often seen as economically or politically different from the North. The word even appears in culture and games. In the card game bridge, one player is called South. This player partners with North to play against East and West. In Greek religion, the south wind was known as Notos. Notos was believed to be the bringer of storms during late summer and autumn.
