'left' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.

'province to sulk about exercise day' is the wordplay.
'province' becomes 'NI' (short for Northern Ireland, a province of the UK).
'to sulk' becomes 'pout' (synonyms).
'about' means one lot of letters goes inside another.
'exercise' becomes 'pe' (Physical Education).
'day' becomes 'd' (abbreviation for day).
'pe'+'d'='ped'
'pout' enclosing 'ped' is 'ppedout'.
'ni'+'ppedout'='NIPPED OUT'
