Prophet penning note: “It’s an unfortunate look” (5)
I believe the answer is:
sneer
'an unfortunate look' is the definition.
'sneer' can be an answer for 'look' (I have seen 'Contemptuous look ' mean 'sneer' so perhaps 'look' could also mean 'sneer'). I am unsure of the 'an unfortunate' bit.
'prophet penning note' is the wordplay.
'prophet' becomes 'seer' (both can mean someone who tells the future).
'penning' is an insertion indicator.
'note' becomes 'n' (abbreviation).
'seer' going around 'n' is 'SNEER'.
'it's' acts as a link.
Can you help me to learn more?
(Other definitions for sneer that I've seen before include "Speak scornfully" , "Contemptuous look" , "Taunt" , "Contemptuous expression" , "A scornful expression or remark" .)
