Shift anger due to being too young (8)
I believe the answer is:
underage
'being too young' is the definition.
(I've seen this before)
'shift anger due' is the wordplay.
'shift' indicates an anagram.
'anger'+'due'='angerdue'
'angerdue' with letters rearranged gives 'UNDERAGE'.
'to' is the link.
(Other definitions for underage that I've seen before include "Not old enough to exercise legal right" , "Immature" , "Not yet eligible to vote - too young" , "Too tender" , "Not legally old enough" .)
