Sung or spoken at church (6)
I believe the answer is:
choral
'sung' is the definition.
(I've seen this before)
'spoken at church' is the wordplay.
'spoken' becomes 'oral' (similar in meaning).
'at' says to put letters next to each other (I've seen this in other clues).
'church' becomes 'ch' (common abbreviation).
'oral' put after 'ch' is 'CHORAL'.
'or' is the link.
(Other definitions for choral that I've seen before include "... his ninth ..." , "Sung psalm" , "Music for groups of singers" , "Involving many singers" , "For a large number of voices" .)
