Dull elegist by the sounds of it (4)
I believe the answer is:
grey
'dull' is the definition.
(I've seen this before)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for grey that I've seen before include "Gloomy colour" , "showing his age?" , "White horse" , "Anonymous" , "Nondescript; overcast (sky)" .)
