The star is upset by apparent dangers (7)
I believe the answer is:
threats
'apparent dangers' is the definition.
'threats' can be an answer for 'dangers' (threat is a kind of danger). I am not sure about the 'apparent' bit.
'the star is upset by' is the wordplay.
'is upset by' is an anagram indicator.
'the'+'star'='thestar'
'thestar' with letters rearranged gives 'THREATS'.
Can you help me to learn more?
(Other definitions for threats that I've seen before include "Menacing statements" , "Sources of danger -- shatter (anag)" , "Expressions of intention to harm" , "Terrifying demands" , "Shatter (anag) - menaces" .)
