Pay for the loud music Dora’s upset about (6)
I believe the answer is:
afford
'pay' is the definition.
(thesaurus)
'the loud music dora's upset about' is the wordplay.
'the loud' becomes 'f' (A musical term).
'music' becomes 'f' (**).
'upset' indicates an anagram.
'about' is an insertion indicator.
'dora' with letters rearranged gives 'aord'.
'f'+'f'='ff'
'ff' put within 'aord' is 'AFFORD'.
'for' is the link.
(Other definitions for afford that I've seen before include "Be able to buy" , "Yield!" , "Have the means to pay" , "Be able to spare the money" , "Able to bear the expense" .)
