Said to be placed amid wild deer (7)
I believe the answer is:
reputed
'said' is the definition.
(thesaurus)
'placed amid wild deer' is the wordplay.
'placed' becomes 'put' (I've seen this in other clues).
'amid' is an insertion indicator.
'wild' indicates anagramming the letters.
'deer' with letters rearranged gives 'reed'.
'put' put inside 'reed' is 'REPUTED'.
'to be' acts as a link.
(Other definitions for reputed that I've seen before include "Generally believed (to be the case)" , "Regarded as such" , "Generally believed to exist" , "Considered" , "Erupted (anag)" .)
