Quiet part of church with plant in (7)
I believe the answer is:
appease
'quiet' is the definition.
(I've seen this in another clue)
'church with plant in' is the wordplay.
'church' becomes 'apse' (I've seen this before).
'with' is an insertion indicator.
'plant in' becomes 'pea' (pea plant is a kind of plant. I am not sure about the 'in' bit.).
'apse' enclosing 'pea' is 'APPEASE'.
'part of' acts as a link.
Can you help me to learn more?
(Other definitions for appease that I've seen before include "be satisfying" , "Satisfy demands by making concessions" , "Placate (someone) by agreeing to their demands" , "Calm, pacify, placate" , "Pacify with concessions" .)
