As humour, it has point (3)
I believe the answer is:
wit
'as humour' is the definition.
'wit' can be an answer for 'humour' (I've seen this before). I'm unsure of the 'as' bit.
'it has point' is the wordplay.
'has' is a charade indicator (letters next to each other).
'point' becomes 'w' (W is an example).
'it' after 'w' is 'WIT'.
Can you help me to learn more?
(Other definitions for wit that I've seen before include "Quickness at clever remarks" , "Nous" , "Acuity" , "Intelligence; humorist" , "Humour or mental capacity" .)
