Women and others left at home, good for sport (9)
I believe the answer is:
wrestling
'for sport' is the definition.
(wrestling is a kind of sport)
'women and others left at home good' is the wordplay.
'women' becomes 'w' (standard abbreviation).
'and others' becomes 'rest' (I've seen this in other clues).
'left' becomes 'l' (common abbreviation).
'at home' becomes 'in' ('I'm in' can mean 'I'm at home').
'good' becomes 'g' (abbreviation).
'w'+'rest'+'l'+'in'+'g'='WRESTLING'
(Other definitions for wrestling that I've seen before include "Ring sport" , "Hand-to-hand combat" , "event" , "gripping contest" , "Hand-to-hand grappling" .)
