Salesman going in without hesitation, feeling sorry (9)
I believe the answer is:
repenting
'salesman going' is the definition.
Although both the answer and definition are present participle verbs, I can't understand how one could define the other.
'in without hesitation feeling sorry' is the wordplay.
I cannot quite understand how this works, but
'in' is within the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Another definition for repenting that I've seen is " showing remorse".)
