For every church has somewhere to sit (5)
I believe the answer is:
perch
'to sit' is the definition.
(I know that perch is a more specific form of sit)
'for every church' is the wordplay.
'for every' becomes 'per' ('per' means 'for each' or 'for every').
'church' becomes 'ch' (abbreviation on maps etc).
'per'+'ch'='PERCH'
'has somewhere' is the link.
This may not be right. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for perch that I've seen before include "What angler may catch" , "Fish; pole" , "Rod, pole or - -" , "bird comes down on" , "Freshwater fish - roost" .)
