Pitches in Italian town cut by good person going round (7)
I believe the answer is:
assists
'pitches in' is the definition.
(I've seen this in another clue)
'italian town cut by good person going round' is the wordplay.
'italian town' becomes 'assisi' (I've seen this before).
'cut' means to remove the last letter.
'by' is a charade indicator (letters next to each other).
'good person' becomes 'st' (saint).
'going round' says the letters should be written backwards.
'st' in reverse letter order is 'ts'.
'assisi' with its last letter removed is 'assis'.
'assis'+'ts'='ASSISTS'
(Other definitions for assists that I've seen before include "Provides" , "Lends a hand" , "Aids" , "Contributes to success" , "Helps or waits on" .)
