Drinks to ghosts
I believe the answer is:
spirits
This could be a double definition.
'drinks' is the first definition.
Although both the answer and definition are verbs in their -s form, I don't understand how one could define the other.
'to ghosts' is the second definition.
(I've seen this in another clue)
Can you help me to learn more?
(Other definitions for spirits that I've seen before include "Ghosts" , "hard stuff?" , "eg Gin, whisky" , "Morale" , "shorts" .)
