After five, evening walks do lift the spirit! (5)
I believe the answer is:
vodka
'the spirit' is the definition.
(I've seen this before)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for vodka that I've seen before include "Spirit made from rye, wheat or potatoes" , "Russian "little water"" , "Russian tipple" , "Distilled spirit" , "Russian liquor" .)
