A servant of magical appearance (5)

I believe the answer is:

genie

I'm a little stuck... Click here to teach me more about this clue!

'a servant' is the definition.
(I have seen 'Magical servant ' mean 'genie' so perhaps 'servant' could also mean 'genie')

I cannot understand how the rest of the clue works.

Can you help me to learn more?

(Other definitions for genie that I've seen before include "Arabian sprite" , "Magician residing in a lamp" , "He came from Aladdin's lamp" , "Goblin as found in Aladdin's lamp" , "Magical being who carries out a person's wishes" .)

I've seen this clue in the Evening Standard.
