Income of the sort of writers I get on with (7)
I believe the answer is:
pension
'income' is the definition.
(I have seen 'Retired income ' mean 'pension' so perhaps 'income' could also mean 'pension')
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for pension that I've seen before include "support for the elderly" , "Nice little hotel" , "Retiree's income" , "Payment to retired persons a continental boarding house" , "Income in retirement" .)
