A more thorough explanation:

Definition: Meta is a Latin word that has two meanings. Firstly, it refers to the mark where a racecourse ends or where chariots turn. Secondly, it means a boundary or border.

• During the chariot race, the drivers had to turn around the meta at the end of the track.
• The river forms the meta between the two countries.

The first example shows how meta was used in ancient Rome to refer to the end point of a racecourse. The second example illustrates how meta can also mean a boundary or border between two places.
