Goddess in heaven, usually (5)
I believe the answer is:
venus
'goddess' is the definition.
(thesaurus)
'in heaven usually' is the wordplay.
'in' indicates the answer is hidden within the clue.
'VENUS' can be found hidden inside 'heaven usually'.
(Other definitions for venus that I've seen before include "Heavenly body" , "The embodiment of Love" , "our Neighbour" , "Roman goddess of love" , "Next planet in" .)
