Inactive liquor apparatus (5)
I believe the answer is:
still
This clue might be a double definition.
'inactive' is the first definition.
('still' can be a synonym of 'inactive')
'liquor apparatus' is the second definition.
'still' can be an answer for 'apparatus' (still is a kind of apparatus). I am not certain of the 'liquor' bit.
Can you help me to learn more?
(Other definitions for still that I've seen before include "It's not effervescing" , "... [STRONG LIQUOR] produced by this" , "activity of one manufacturing spirits?" , "Source of alcohol" , "Snap" .)
