Regret love affair after abandoning a maiden finally (5)
I believe the answer is:
mourn
'regret' is the definition.
(I've seen this before)
'love affair after abandoning a maiden finally' is the wordplay.
I cannot really understand how this works, but
'love' could be 'o' (love means zero in tennis) and 'o' is located in the answer.
'maiden' could be 'm' (cricket abbreviation) and 'm' is present in the answer.
The remaining letters 'urn' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for mourn that I've seen before include "Express sadness" , "Grieve for a death" , "'Miss'" , "Lament loss" , "Show sorrow at death" .)
