Hesitate to be unreasonably rude about James Bond's boss (5)
I believe the answer is:
demur
'hesitate' is the definition.
(I've seen this in another clue)
'unreasonably rude about james bond's boss' is the wordplay.
I cannot really understand how this works, but
'bond's boss' could be 'm' (M is the head of MI6 in the James Bond series) and 'm' is found in the answer.
an anagram of 'rude' is 'deur' which is located in the remaining letters.
This accounts for all the letters.
This explanation may well be incorrect...
'to be' is the link.
Can you help me to learn more?
(Other definitions for demur that I've seen before include "Hesitation" , "Object gently" , "Take exception (to)" , "Raise mild objection" , "Protest mildly, show reluctance" .)
