Raising the issue about being choked by breathlessness (9)
I believe the answer is:
parenting
'raising the issue' is the definition.
'parenting' can be an answer for 'raising' ('parent' can be a synonym of 'raise'). I'm not sure about the 'the issue' bit.
'about being choked by breathlessness' is the wordplay.
'about' becomes 're' (regarding).
'being choked by' is an insertion indicator (I've seen this in other clues).
'breathlessness' becomes 'panting' (I can't explain this - if you can you should believe this answer much more).
're' placed within 'panting' is 'PARENTING'.
Can you help me to learn more?
(Other definitions for parenting that I've seen before include "mom and pop art?" , "Being a mum say" .)
