Dread fare changes (4)
I believe the answer is:
fear
'dread' is the definition.
(I know that dread can be written as fear)
'fare changes' is the wordplay.
'changes' indicates anagramming the letters.
'fare' is an anagram of 'FEAR'.
(Other definitions for fear that I've seen before include "Cutting edge" , "Apprehension" , "Anxiety caused by danger" , "Consternation" , "Terror" .)
