Excellent woman, right? (7)
I believe the answer is:
stellar
'excellent' is the definition.
(I've seen this in another clue)
'woman right?' is the wordplay.
I cannot quite see how this works, but
'woman' could be 'stella' and 'stella' is located in the answer.
'right?' could be 'r' (abbreviation) and 'r' is located in the answer.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for stellar that I've seen before include "Outstanding -- star-like" , "Starry" , "Top-notch" , "Exceptionally good" , "celebrity" .)
