Doctor bears arms -- shame! (9)
I believe the answer is:
embarrass
'shame' is the definition.
(thesaurus)
'doctor bears arms' is the wordplay.
'doctor' indicates an anagram.
'bears'+'arms'='bearsarms'
'bearsarms' with letters rearranged gives 'EMBARRASS'.
(Other definitions for embarrass that I've seen before include "Cause (someone) to feel awkward" , "Show up" , "Make uncomfortable" , "Abash" , "Cause to feel ashamed" .)
