What does southing mean?
Southing is a formal noun for movement or position in a southerly direction. It can describe the process of proceeding south, the distance covered toward the south, or a point's latitude south of a reference. The word is especially associated with navigation, surveying, and geography, where a vessel's course or position may be described in terms of southing or northing. Its counterpart, northing, applies to movement or distance toward the north. Although southing is grammatically straightforward, it is uncommon in everyday English, where phrases such as southward movement or distance south are usually more natural. The term is nevertheless useful because it precisely identifies a directional relationship without necessarily naming a particular route, speed, or method of travel. It can also distinguish a measured change in latitude from a simple general reference to the south.
nounThe act or process of moving or extending southward, especially as described in navigation. It can also denote the distance or difference in latitude south of a specified point.
- The act or process of moving or extending southward.

"The ship's changing southing was recorded throughout the voyage."
"The pilots estimated the vessel's southing before the storm reached them."

The plural is rare; southing is more often treated as an uncountable noun when referring to a process or measured distance.

In navigation, a southing can be the invisible line that leads a ship southward—and a measurable stretch of that journey.

Where does southing come from?
Southing was formed in English in the late 16th century from the established directional word south and the suffix -ing. The older element south continues Old English sūþ, which derives from the same Proto-Germanic root found in related Germanic languages. English subsequently developed several derivatives from this root, including southerly, southern, and southwest.
