Man of vision, sounding old and withered (4)
I believe the answer is:
seer
'man of vision' is the definition.
The answer and definition can be both people as well as being singular nouns.
Maybe there's a link between them I don't understand?
'sounding old and withered' is the wordplay.
I cannot quite see how this works, but
'sounding' could be 'e' (I've seen this in other clues) and 'e' is found within the answer.
The remaining letters 'ser' 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 seer that I've seen before include "Sibyl" , "I envisage" , "One fortelling future" , "Prophet or visionary" , "Prophet, one who has visions" .)
