Weak dove going west shows spirit (5)
I believe the answer is:
vodka
'spirit' is the definition.
(I've seen this before)
'weak dove going west shows' is the wordplay.
'shows' indicates the answer is hidden within the clue.
'going west' says the letters should be written backwards (letters heading to the west or left).
'akdov' can be found hidden inside 'weak dove'.
'akdov' written backwards gives 'VODKA'.
(Other definitions for vodka that I've seen before include "Russian liquor" , "Booze" , "Alcoholic spirit of Russian origin" , "Russian alcoholic drink" , "Distilled spirit" .)
