Get paid some peanuts for a service (4)
I believe the answer is:
earn
'get paid' is the definition.
(I've seen this before)
'some peanuts for a service' is the wordplay.
'some peanuts for' becomes 'ea' (I can't justify this - if you can you should give a lot more credence to this answer).
'a service' becomes 'RN' (abbreviation for Royal Navy).
'ea'+'rn'='EARN'
Can you help me to learn more?
(Other definitions for earn that I've seen before include "long gone" , "Acquire by one's efforts" , "Deserve, gain" , "Be paid for work" , "Merit (a reward)" .)
