Clairvoyant one (4)
I believe the answer is:
seer
'clairvoyant one' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for seer that I've seen before include "Sage with 20ac" , "Distinguishing quality" , "Person of vision" , "wise fellow" , "Regard with respect" .)
