Prophet pens new and hostile remark (5)
I believe the answer is:
sneer
'hostile remark' is the definition.
'sneer' can be an answer for 'remark' (I have seen 'Contemptuous remark ' mean 'sneer' so perhaps 'remark' could also mean 'sneer'). I am not certain of the 'hostile' bit.
'prophet pens new' is the wordplay.
'prophet' becomes 'seer' (both can mean someone who tells the future).
'pens' indicates putting letters inside.
'new' becomes 'n' (common abbreviation eg NT for New Testament).
'seer' enclosing 'n' is 'SNEER'.
'and' acts as a link.
Can you help me to learn more?
(Other definitions for sneer that I've seen before include "Contemptuous gesture" , "Taunt" , "Speak contemptuously" , "Curl one's lip" , "Dig" .)
