Something seen in heaven, usually (5)
I believe the answer is:
venus
'something seen' 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 in the letters of 'heaven usually'.
Can you help me to learn more?
(Other definitions for venus that I've seen before include "Heavenly body" , "Brightest planet" , "our Neighbour" , "Morning star" , "One of the planets" .)
