Eggs on reserve in handy container (6,3)
I believe the answer is:
clutch bag
'handy container' is the definition.
'clutch bag' can be an answer for 'container' (clutch bag is a kind of container). I am not sure about the 'handy' bit.
'eggs on reserve' is the wordplay.
'eggs' becomes 'clutch' (group of bird eggs).
'on' says to put letters next to each other.
'reserve' becomes 'bag'.
'clutch'+'bag'='CLUTCH BAG'
'in' is the link.
Can you help me to learn more?
(Other definitions for clutch bag that I've seen before include "where lady keeps her things" , "Woman's strapless fashion accessory" .)
