This year is set for emotional outburst (8)
I believe the answer is:
hysteria
'emotional outburst' is the definition.
(I've seen this in another clue)
'this year is set' is the wordplay.
'is set' indicates an anagram (instruction to set the letters).
'this'+'year'='thisyear'
'thisyear' with letters rearranged gives 'HYSTERIA'.
'for' acts as a link.
(Other definitions for hysteria that I've seen before include "Panic" , "highly emotional state" , "craze" , "Frenzied emotional state" , "Uncontrollable emotion -- this year (anag)" .)
