Exceptionally good woman meets resistance (7)
I believe the answer is:
stellar
'exceptionally good' is the definition.
(I've seen this before)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for stellar that I've seen before include "Top-notch" , "Excellent - shining bright?" , "boss!" , "of celebrities" , "Like highlights" .)
