I'm a little stuck... Click here to teach me more about this clue!

'bitter twist' is the definition.
'rancorous' can be an answer for 'bitter' (I've seen this before). I am unsure of the 'twist' bit.

'our scorn about the answer' is the wordplay.
'about' indicates anagramming the letters.
'the answer' becomes 'a' (abbreviation eg in Q and A).
'our'+'scorn'='ourscorn'
'ourscorn' anagrammed with 'a' can make 'RANCOROUS'.

'to' acts as a link.

Can you help me to learn more?

(Other definitions for rancorous that I've seen before include "Acrimonious" , "Resentful, bitter" , "spiteful?" , "Showing bitter resentment" .)
