Getting winded is so exhilarating (12)
I believe the answer is:
breathtaking
'exhilarating' is the definition.
(thesaurus)
'getting winded is' is the wordplay.
I cannot quite see how this works, but
'getting' could be 'taking' ('take' can be a synonym of 'get') and 'taking' is found in the answer.
The remaining letters 'breath' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
'so' is the link.
Can you help me to learn more?
(Other definitions for breathtaking that I've seen before include "Awe-inspiring" , "Causing astonishment" , "Awesome" , "Astounding" , "Moving" .)
