Allowance for no spine injury (7)
I believe the answer is:
pension
'allowance' is the definition.
(thesaurus)
'no spine injury' is the wordplay.
'injury' indicates an anagram.
'no'+'spine'='nospine'
'nospine' anagrammed gives 'PENSION'.
'for' is the link.
(Other definitions for pension that I've seen before include "Retired person's income" , "Income in retirement" , "Bed and breakfast or small hotel in France" , "Retirement pay in a Continental boarding-house" , "Payment to retired persons a continental boarding house" .)
