Special ceremony summons goblin? (6)
I believe the answer is:
sprite
'summons goblin?' is the definition.
'sprite' can be an answer for 'goblin?' (I've seen this in another clue). I'm not certain of the 'summons' bit.
'special ceremony' is the wordplay.
'special' becomes 'sp' (abbreviation).
'ceremony' becomes 'rite' (rite is a kind of ceremony).
'sp'+'rite'='SPRITE'
Can you help me to learn more?
(Other definitions for sprite that I've seen before include "Goblin, elf or imp" , "Elf, fairy" , "Nimble elf-like creature - icon in computer game" , "water pixie" , "Pet, sir, could be a goblin" .)
