Squirreled away
I believe the answer is:
hid
'squirreled away' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for hid that I've seen before include "Concealed in orchids" , "Remained out of sight" , "wanted to be sought?" , "Concealed from sight" , "Concealed (oneself?)" .)
