Attempt to limit ruin with it (6)
I believe the answer is:
trendy
'with it' is the definition.
(thesaurus)
'attempt to limit ruin' is the wordplay.
'attempt' becomes 'try' (I've seen this before).
'to limit' means one lot of letters goes inside another.
'ruin' becomes 'end' (ruin something means to end it).
'try' going around 'end' is 'TRENDY'.
(Other definitions for trendy that I've seen before include "Informally, following the fashions" , "following latest convention" , "Informally fashionable" , "following fashion" , "Up to date, fashionable" .)
