Former Welsh rite recreated (9)
I believe the answer is:
erstwhile
'former' is the definition.
(I know that former can be written as erstwhile)
'welsh rite recreated' is the wordplay.
'recreated' indicates an anagram.
'welsh'+'rite'='welshrite'
'welshrite' is an anagram of 'ERSTWHILE'.
(Other definitions for erstwhile that I've seen before include "Quondam" , "Former, previous" , "In the past" , "Formerly" , "Former - list where (anag)" .)
