Woman in front of redhead is heavenly! (7)
I believe the answer is:
stellar
'heavenly' is the definition.
(thesaurus)
'woman in front of redhead' is the wordplay.
I cannot really see how this works, but
'woman' could be 'stella' and 'stella' is present in the answer.
'redhead' could be 'r' (the head/first letter of 'red') and 'r' is present in the answer.
No letters remain.
This may be the basis of clue (or it may be nonsense).
'is' is the link.
Can you help me to learn more?
(Other definitions for stellar that I've seen before include "Relating to the stars" , "Astral" , "Starry" , "characteristic of The Sun, etc" , "Star-like, with star quality" .)
