Admired revolutionary put off eating mushrooms (9)
I believe the answer is:
respected
'admired' is the definition.
(thesaurus)
'revolutionary put off eating mushrooms' is the wordplay.
'revolutionary' is a reversal indicator (letters revolve around).
'put off' becomes 'deter' (both can mean to discourage).
'eating' means one lot of letters goes inside another.
'mushrooms' becomes 'ceps' (cep is a type of mushroom).
'deter' placed around 'ceps' is 'detcepser'.
'detcepser' back-to-front is 'RESPECTED'.
(Other definitions for respected that I've seen before include "Regarded highly" , "Held in high regard" , "Held in esteem" , "Had a high regard for someone" , "Looked up to" .)
