Sense: noun/1
All four terms refer to a way of describing a position on a map or diagram, but they differ in precision and context. "Co-ord" is an informal shortening of "coordinate" used mainly in British English speech and casual writing — for example, a teacher telling a class "the cave is at co-ord D4." "Grid reference" is the standard British term for the numbered grid system on Ordnance Survey maps and is more formal and precise; a hiker would say "the grid reference is SU 123 456." "Map reference" is broader and can include place names, landmarks, or a combination of methods, not just a numbered grid. "Location point" is a general term used in digital contexts such as GPS coordinates or software interfaces. In practice, choose "co-ord" for informal British conversations about maps or graphs, "grid reference" for formal navigation, and "map reference" for mixed-media instructions.

Etymology
Co-ord is a clipped form of the noun "coordinate," which entered English in the mid-17th century from the Latin "coordinatus" ("co-" meaning "together" and "ordinare" meaning "to arrange"). The noun sense meaning "location point on a map" dates from the 19th century, while the clothing sense emerged in the 20th-century fashion industry. The abbreviation of "coordination" to "co-ord" follows the same shortening pattern and is found in British business writing from the mid-20th century onward.
