Savings for old age, for short (3)
I believe the answer is:
ira
'savings for old age for short' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for ira that I've seen before include "Brother of George Gershwin" , "George Gershwin's older brother, the lyricist" , "Songwriter George's elder brother" , "nationalists" , "terrorists" .)
