It's fresh out (3)
I believe the answer is:
air
'it's' is the definition.
I can't judge whether this defines the answer.
'fresh out' is the wordplay.
'fresh' becomes 'airy' (I've seen this in another clue).
'out' means to remove the last letter.
'airy' with its final letter taken off is 'AIR'.
Can you help me to learn more?
(Other definitions for air that I've seen before include "Mix of gases surrounding the earth" , "- - on a G-string" , "Expose" , "in which birds fly around" , "Simple composition" .)
