Seer's location (3,6)
I believe the answer is:
eye socket
'seer's' is the definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.
'location' is the wordplay.
I cannot really understand how this works, but
'location' could be 'eye' (eye is a kind of location) and 'eye' is located in the answer.
The remaining letters 'socket' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for eye socket that I've seen before include "Orbit (anatomy)" , "Hole for viewing organ" , "Here viewer's set" , "Cavity for sight organ" .)
