Company call to stop charging everyone for drink (7)
I believe the answer is:
alcohol
'for drink' is the definition.
(alcohol is a kind of drink)
'company call to stop charging' is the wordplay.
'company' becomes 'co' (abbreviation).
'call' becomes 'ho' (historical exclamation used to attract attention).
'to stop' is an insertion indicator (stopping can mean blocking a gap).
'charging' becomes 'all' (I can't explain this - if you can you should give a lot more credence to this answer).
'co'+'ho'='coho'
'coho' inserted inside 'all' is 'ALCOHOL'.
'everyone' acts as a link.
This may not be right. It may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for alcohol that I've seen before include "Intoxicating liquid" , "Booze" , "Strong drink" , "Source of intoxication" , "lager, perhaps" .)
