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 unsure of the 'the issue' bit.
'about being choked by breathlessness' is the wordplay.
'about' becomes 're' ('re' means regarding or about).
'being choked by' indicates putting letters inside (I've seen this in other clues).
'breathlessness' becomes 'panting' (I can't justify this - if you can you should give a lot more credence to this answer).
're' going into '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" .)
