Spirit in bottle in Egypt sent westward (5)
I believe the answer is:
genie
'spirit' is the definition.
(I know that genie is a type of spirit)
'in bottle in egypt sent westward' is the wordplay.
'in' indicates a hidden word.
'westward' shows that the letters should be reversed in order.
'eineg' is hidden in the letters of 'bottle in egypt sent'.
'eineg' reversed gives 'GENIE'.
(Other definitions for genie that I've seen before include "Arabian goblin with magic powers" , "Helpful (?) spirit" , "Bottled spirit?" , "Magical servant" , "In Arabian Nights, a magic goblin" .)
