Some areas, typically, are right on the map (4)
I believe the answer is:
east
'right on the map' is the definition.
The definition and answer can be both relationships as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'some areas typically are' is the wordplay.
'some' indicates the answer is hidden within the clue (some of the parts of the word are used).
'EAST' is hidden within 'areas typically are'.
Can you help me to learn more?
(Other definitions for east that I've seen before include "Oriental lands" , "Where the sun rises" , "On most maps it's right!" , "playing partner" , "Towards the dawn" .)
