Gets gen about savings (4,3)
I believe the answer is:
nest egg
'savings' is the definition.
('nest egg' can be a synonym of 'savings')
'gets gen about' is the wordplay.
'about' indicates an anagram.
'gets'+'gen'='getsgen'
'getsgen' is an anagram of 'NEST-EGG'.
(Other definitions for nest egg that I've seen before include "money put away" , "Is it to encourage laying" , "Reserve funds" , "Retirement savings" , "a little money?" .)
