Recording evil spirit briefly (4)
I believe the answer is:
demo
'recording' is the definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.
'evil spirit briefly' is the wordplay.
'evil spirit' becomes 'demon' (demon is a kind of evil spirit).
'briefly' means to remove the last letter.
'demon' with its final letter removed is 'DEMO'.
Can you help me to learn more?
(Other definitions for demo that I've seen before include "March (abbr)" , "Show" , "Protest (abbr)" , "illustration" , "Eg, protest march" .)
