Providing corrective action in respect of me fizzling out (9)
I believe the answer is:
remedying
'providing corrective action' is the definition.
I can't tell whether this defines the answer.
'respect of me fizzling out' is the wordplay.
'respect of' becomes 're' ('re' means regarding or about).
'fizzling out' becomes 'dying' (I've seen this in another clue).
're'+'me'+'dying'='REMEDYING'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for remedying that I've seen before include "sorting out" , "Putting right (an undesirable situation)" .)
