Emotionally-charged writer set to return (4-2)
I believe the answer is:
pent-up
'emotionally-charged' is the definition.
I can't judge whether this definition defines the answer.
'writer set to return' is the wordplay.
'writer' becomes 'pen' (something which writes).
'set' becomes 'put' (synonyms).
'to return' shows that the letters should be reversed in order.
'put' backwards is 'tup'.
'pen'+'tup'='PENT-UP'
Can you help me to learn more?
(Other definitions for pent-up that I've seen before include "Dammed or repressed" , "Repressed, emotions say" , "Closely confined" , "Confined like feelings or water behind dam" , "Russian city" .)
