Difficult to dismiss source of regret in a draw (5)
I believe the answer is:
tying
'a draw' is the definition.
The definition and answer can be both acts as well as being singular nouns.
Maybe you can see an association between them that I don't see?
'difficult to dismiss source of regret in' is the wordplay.
I cannot quite understand how this works, but
'in' is found in the answer.
The remaining letters 'tyg' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for tying that I've seen before include "Scoring the same" , "Restricting" , "lacing" , "Linking" , "Binding, fastening" .)
