Always restricted by right objective for cleric (8)
I believe the answer is:
reverend
'cleric' is the definition.
(I've seen this before)
'always restricted by right objective' is the wordplay.
'always' becomes 'ever' ('ever' can be a synonym of 'always').
'restricted by' indicates putting letters inside (I've seen this in other clues).
'right' becomes 'r' (common abbreviation).
'objective' becomes 'end' (I've seen this before).
'r'+'end'='rend'
'ever' put into 'rend' is 'REVEREND'.
'for' is the link.
(Other definitions for reverend that I've seen before include "(Form of address to) clergyman" , "Priest" , "Clergyman's title" , "Minister" , "Style of cleric" .)
