Find Charlie at church (5)
I believe the answer is:
catch
'find' is the definition.
(I know this)
'charlie at church' is the wordplay.
'charlie' becomes 'c' (phonetic alphabet: alpha, bravo, charlie etc.).
'church' becomes 'ch' (common abbreviation).
'c'+'at'+'ch'='CATCH'
(Other definitions for catch that I've seen before include "problem being concealed" , "Grab; disadvantage" , "Snare, entrap" , "Seize; start burning" , "potential partner?" .)
