Deity in heaven, usually (5)
I believe the answer is:
venus
'deity' is the definition.
(Venus is an example)
'in heaven usually' is the wordplay.
'in' says the answer is hidden in the clue.
'VENUS' can be found hidden inside 'heaven usually'.
(Other definitions for venus that I've seen before include "Solar system planet" , "Aggrieved, peeved" , "Second nearest planet to the sun" , "Next planet in" , "not really a star" .)
