Jeer receiving writer's tip for facetious title (3,4)
I believe the answer is:
his nibs
'facetious title' is the definition.
'his nibs' can be an answer for 'title' (I have seen 'Mock title ' mean 'his nibs' so perhaps 'title' could also mean 'his nibs'). I am not certain of the 'facetious' bit.
'jeer receiving writer's tip' is the wordplay.
'jeer' becomes 'hiss' (I've seen this before).
'receiving' means one lot of letters goes inside another.
'writer's tip' becomes 'nib' (I've seen this in another clue).
'hiss' placed around 'nib' is 'HIS NIBS'.
'for' is the link.
Can you help me to learn more?
(Other definitions for his nibs that I've seen before include "Mockingly, a pompous person" , "used by a male author?" , "Mock title for a self-important chap" , "very important person" , "person plagued by pomposity" .)
