Throw it in front of parish church (5)
I believe the answer is:
pitch
'throw' is the definition.
(pitch is a kind of throw)
'it in front of parish church' is the wordplay.
'in' means one lot of letters goes inside another.
'front of' suggests taking the first letters.
'church' becomes 'ch' (common abbreviation).
The initial letter of 'parish' is 'p'.
'p'+'ch'='pch'
'it' inserted inside 'pch' is 'PITCH'.
(Other definitions for pitch that I've seen before include "Erect (tent); steepness of roof" , "Hurl" , "Slope, of a roof say" , "-- and putt" , "Playing field as for football" .)
