Evening prayer gets some wives perhaps (6)
I believe the answer is:
vesper
'evening prayer' is the definition.
(I've seen this before)
'some wives perhaps' is the wordplay.
'some' indicates the answer is hidden within the clue (some of the parts of the word are used).
'VESPER' can be found hidden inside 'wives perhaps'.
'gets' acts as a link.
(Other definitions for vesper that I've seen before include "Evening worship service" , "Evening bell" , "Evening prayer" .)
