Judges fellow at church (5)
I believe the answer is:
bench
'judges' is the definition.
(name for a judge's seat, or for judges themselves)
'fellow at church' is the wordplay.
'fellow' becomes 'ben' (I can't explain this - if you can you should give a lot more credence to this answer).
'at' means one lot of letters go next to another.
'church' becomes 'ch' (abbreviation on maps etc).
'ben'+'ch'='BENCH'
Can you help me to learn more?
(Other definitions for bench that I've seen before include "Magistrates collectively" , "Long seat or worktable" , "Laboratory work table" , "Long seat for judges" , "Group of magistrates" .)
