Looked good, grounds outside church (7)
I believe the answer is:
glanced
'looked' is the definition.
(glancing is a kind of looking)
'good grounds outside church' is the wordplay.
'good' becomes 'g' (abbreviation).
'grounds' becomes 'land'.
'outside' is an insertion indicator.
'church' becomes 'ce' (abbreviation for Church of England).
'land' enclosing 'ce' is 'lanced'.
'g'+'lanced'='GLANCED'
(Other definitions for glanced that I've seen before include "Looked briefly or bounced off" , "Peeked" , "Looked quickly" , "Took a quick look" , "Glimpsed" .)
