Bully Vicar’s hard to replace, right? (6)
I believe the answer is:
hector
'bully' is the definition.
(synonyms)
'vicar's hard to replace right?' is the wordplay.
I cannot quite see how this works, but
'hard' could be 'h' (abbreviation used in pencil classifications) and 'h' is located in the answer.
'to' is found in the answer.
'right?' could be 'r' (common abbreviation) and 'r' is located in the answer.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for hector that I've seen before include "'Browbeat, ballyrag (6)'" , "one of the 4 [TROJAN]s by 28 [BERLIOZ] ?" , "Trojan hero - bully" , "Nag" , "Browbeat, bully" .)
