Pale sort of ring (4)
I believe the answer is:
peal
'ring' is the definition.
(I know that ring can be written as peal)
'pale sort' is the wordplay.
'sort' indicates an anagram.
'pale' with letters rearranged gives '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" .)
