Menaces troubled the star (7)
I believe the answer is:
threats
'menaces' is the definition.
('threat' can be a synonym of 'menace')
'troubled the star' is the wordplay.
'troubled' indicates an anagram.
'the'+'star'='thestar'
'thestar' is an anagram of 'THREATS'.
(Other definitions for threats that I've seen before include "Sources of danger -- shatter (anag)" , "Expressions of intention to harm" , "Shatter (anag) - menaces" , "Terrifying demands" , "Statements of intentions to harm" .)
