Bad feeling about sob stuff putting one off (10)
I believe the answer is:
resentment
'bad feeling' is the definition.
'resentment' can be an answer for 'feeling' (resentment is a kind of feeling). I am unsure of the 'bad' bit.
'about sob stuff putting one off' is the wordplay.
I cannot quite understand how this works, but
'about' could be 're' ('re' means regarding or about) and 're' is found in the answer.
'one' could be 'me' (a setter might use 'one' to humourously mean 'me') and 'me' is found in the answer.
'stuff' could be 'tnt' (TNT is an example) and 'tnt' is found within the remaining letters.
The remaining letters 'sen' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for resentment that I've seen before include "Annoyance" , "Grudge" , "Umbrage" , "Hard feelings" , "offence" .)
