Spirit regularly distilled from green rice (5)
I believe the answer is:
genie
'spirit' is the definition.
(I know that genie is a type of spirit)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for genie that I've seen before include "Magician residing in a lamp" , "means of wishfulfilment" , "Goblin as found in Aladdin's lamp" , "Spirit in a bottle" , "Arabian goblin with strange powers" .)
