Dour church with no branches? (9)
I believe the answer is:
charmless
'dour' is the definition.
'church with no branches?' is the wordplay.
'church' becomes 'ch' (common abbreviation).
'with no branches?' becomes 'armless' (arm can mean a branch).
'ch'+'armless'='CHARMLESS'
(Other definitions for charmless that I've seen before include "Lacking any appeal" , "not winning" , "Unattractive" , "Without attractive features" .)
