Self-centred fathead in a pixie hood! (3)
I believe the answer is:
elf
'a pixie hood' is the definition.
'elf' can be an answer for 'hood' (thesaurus). I am unsure of the 'a pixie' bit.
'self-centred fathead' is the wordplay.
'centred' indicates the central letters.
'fathead' becomes 'f' (head letter of 'fat').
The central letters of 'self' are 'el'.
'el'+'f'='ELF'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for elf that I've seen before include "A leprechaun" , "Goblin" , "Mischievous creature" , "Mischievous youngster" , "1 ac fairy" .)
