Bury substitute — talented and transposable (15)
I believe the answer is:
interchangeable
'transposable' is the definition.
(thesaurus)
'bury substitute talented' is the wordplay.
'bury' becomes 'inter' (synonyms).
'substitute' becomes 'change' (changing is a kind of substituting).
'talented' becomes 'able' (I've seen this before).
'inter'+'change'+'able'='INTERCHANGEABLE'
'and' acts as a link.
(Other definitions for interchangeable that I've seen before include "that can be traded in places" , "(Of things) that may be swapped over" .)
