Seem confused about church plan (6)
I believe the answer is:
scheme
'plan' is the definition.
(scheming is a kind of planning)
'seem confused about church' is the wordplay.
'confused' indicates an anagram.
'about' indicates putting letters inside.
'church' becomes 'ch' (common abbreviation).
'seem' is an anagram of 'seme'.
'seme' enclosing 'ch' is 'SCHEME'.
(Other definitions for scheme that I've seen before include "Systematic plan or arrangement" , "Plan (maybe best laid?)" , "Systematic plan, plot" , "Project or strategy" , "Plot, plan secretly" .)
