Pale sort of ring (4)
I believe the answer is:
peal
'ring' is the definition.
(I know that peal is a more specific form of ring)
'pale sort' is the wordplay.
'sort' indicates an anagram.
'pale' is an anagram of 'PEAL'.
'of' acts as a link.
(Other definitions for peal that I've seen before include "Deep prolonged sound" , "Loud burst of thunder - or laughter" , "Pale over sound of bells" , "Prolonged sound of a bell" , "Ring recurrently" .)
