Celestial object in heaven, usually (5)
I believe the answer is:
venus
'celestial object' is the definition.
'Venus' can be an answer for 'object' (Venus is an example). I am unsure of the 'celestial' bit.
'in heaven usually' is the wordplay.
'in' indicates the answer is hidden within the clue.
'VENUS' can be found hidden inside 'heaven usually'.
Can you help me to learn more?
(Other definitions for venus that I've seen before include "Aggrieved, peeved" , "Morning star" , "Planet; goddess" , "Roman counterpart of Aphrodite" , "Brightest planet" .)
