spoilt

Here is my best explanation:

'is ruined' is the definition.
(thesaurus)

'see the one left inside' is the wordplay.
'see' becomes 'spot' (I've seen this before**).
'the one' becomes 'i' (Roman numeral).
'left' becomes 'l' (common abbreviation).
'inside' means one lot of letters goes inside another.
'i'+'l'='il'
'spot' placed around 'il' is 'SPOILT'.
