Some of penalties missed, turning over channel (4)
I believe the answer is:
lane
'channel' is the definition.
(thesaurus)
'some of penalties missed turning over' is the wordplay.
'some of' indicates a hidden word.
'turning over' says the letters should be written in reverse.
'enal' is hidden in the letters of 'penalties missed'.
'enal' backwards is 'LANE'.
(Other definitions for lane that I've seen before include "Passage" , "Quiet road" , "Byroad" , "way" , "Narrow rural road" .)
