Name for a church seat (5)
I believe the answer is:
bench
'seat' is the definition.
(bench is a kind of seat)
'name for a church' is the wordplay.
'name' becomes 'ben' ().
'for' says to put letters next to each other.
'a church' becomes 'ch' (common abbreviation).
'ben'+'ch'='BENCH'
(Other definitions for bench that I've seen before include "Plain, stout work-table" , "Laboratory work table" , "Exhibit at dog show" , "Group of magistrates" , "Long seat for judges" .)
