It's in heaven, usually (5)
I believe the answer is:
venus
'it's' is the definition.
I can't tell whether this defines the answer.
'in heaven usually' is the wordplay.
'in' indicates a hidden word.
'VENUS' is hidden within 'heaven usually'.
Can you help me to learn more?
(Other definitions for venus that I've seen before include "One of the planets" , "our Neighbour" , "Planet; goddess" , "Next planet in" , "Heavenly body" .)
