A frame of reference is a coordinate system used to identify the physical location of an object.
Absolute frame of reference is also a binary system in which the location of an object is defined in relation to arbitrary fixed bearings, such as cardinal directions (North, South, East, West).
For instance, in English, all three are available and used, but the use of absolute frame of reference is limited to topographic objects ("Finland is to the east of Sweden").
For instance, to be able to communicate in a language with absolute frame of reference, speakers have to run a kind of mental compass.
A remarkable neurocognitive capacity allows speakers to identify cardinal directions, even in unfamiliar locations.
