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 before).
'amid' is an insertion indicator.
'wild' is an anagram indicator.
'deer' is an anagram of 'reed'.
'put' inserted into '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)" .)
