In return, gets information about savings (4,3)
I believe the answer is:
nest egg
'savings' is the definition.
('nest egg' can be a synonym of 'savings')
'in return gets information' is the wordplay.
I cannot really see how this works, but
an anagram of 'gets' is 'steg' which is located in the answer.
This may be the basis of clue (or it may be nonsense).
'about' acts as a link.
Can you help me to learn more?
(Other definitions for nest egg that I've seen before include "Savings for the future" , "A saving for the future - by bird?" , "Fund for a rainy day" , "Money saved for the future" , "Money laid aside for some future eventuality" .)
