'Pointy-headed'? 'Sharp' is about right (6)
I believe the answer is:
horned
'pointy-headed'?' is the definition.
I can't tell whether this definition defines the answer.
'sharp is about right' is the wordplay.
'sharp' becomes 'honed' (I've seen this in another clue).
'is about' indicates putting letters inside.
'right' becomes 'r' (common abbreviation).
'honed' placed around 'r' is 'HORNED'.
Can you help me to learn more?
(Other definitions for horned that I've seen before include "Like bulls, rhinos, etc" , "With outgrowths on head" , "-- Owl; -- toad" .)
