Report from a suburban garden (4)
I believe the answer is:
bang
'report' is the definition.
(report can mean a loud noise)
'from a suburban garden' is the wordplay.
'from' indicates the answer is hidden within the clue.
'BANG' is hidden in the letters of 'suburban garden'.
(Other definitions for bang that I've seen before include "precisely" , "Sudden loud noise like an explosion" , "Completely modern" , "Sound of a gunshot" , "Vigorous blow" .)
