Liquor I found in upside-down sports gear (7)
I believe the answer is:
spirits
This clue could be a double definition.
'liquor' is the first definition.
(I know that liquor can be written as spirits)
'i found in upside-down sports gear' is the second definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
(Other definitions for spirits that I've seen before include "Morale" , "Shades" , "Gin, vodka, rum etc" , "Hard liquor" , "Animating forces or hard liquors" .)
