Bit of glory and gold boring dull pope (7)
I believe the answer is:
gregory
'pope' is the definition.
(Gregory is an example)
'bit of glory and gold boring dull' is the wordplay.
'bit of' suggests taking the first letters.
'and' means one lot of letters go next to another.
'gold' becomes 'or' ('or' is the heraldic name for gold).
'boring' means one lot of letters goes inside another (to bore something can mean to drill into it).
'dull' becomes 'grey' (I've seen this before).
The initial letter of 'glory' is 'g'.
'g'+'or'='gor'
'gor' inserted inside 'grey' is 'GREGORY'.
(Other definitions for gregory that I've seen before include "pope, perhaps" , "Calendar-reforming pope" , "boy" , "Boy's name meaning "watcher"" .)
