Be sorry for a doctor given the runaround (5)
I believe the answer is:
mourn
'be sorry' is the definition.
The answer and definition can be both to do with human feelings as well as being verbs in their base form.
Perhaps they are linked in a way I don't understand?
'doctor given the runaround' is the wordplay.
'doctor' becomes 'mo' (medical officer).
'given' is a charade indicator (letters next to each other).
'the runaround' becomes 'urn' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'mo'+'urn'='MOURN'
'for a' acts as a link.
Can you help me to learn more?
(Other definitions for mourn that I've seen before include "'Miss'" , "Keen" , "Weep for" , "Express sadness" , "Show sorrow at death" .)
