Panic diverted this year (8)
I believe the answer is:
hysteria
'panic' is the definition.
(thesaurus)
'diverted this year' is the wordplay.
'diverted' indicates anagramming the letters (each letter get diverted elsewhere).
'this'+'year'='thisyear'
'thisyear' with letters rearranged gives 'HYSTERIA'.
(Other definitions for hysteria that I've seen before include "Delirium - nervous disorder" , "Uncontrollable excitement" , "Panic" , "Emotional and uncontrollable outburst" , "Wild emotionalism" .)
