To revere, yet maybe even to rebuke! (8)
I believe the answer is:
venerate
'to revere' is the definition.
('venerate' can be a synonym of 'revere')
'maybe even to rebuke' is the wordplay.
'maybe' indicates anagramming the letters.
'to rebuke' becomes 'rate' (I can't justify this - if you can you should believe this answer much more).
'even' is an anagram of 'vene'.
'vene'+'rate'='VENERATE'
'yet' acts as a link.
Can you help me to learn more?
(Other definitions for venerate that I've seen before include "Treat with respect" , "Regard with deep respect or worship" , "Regard (something) with great respect" , "Think a great deal of" , "Revere highly" .)
