Delayed expression of approval? (2,3)
I believe the answer is:
on ice
'delayed' is the definition.
(I've seen this in another clue)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for on ice that I've seen before include "kept for later" , "In poky alone" , "held back?" , "Kept in readiness" , "Shelved" .)
