Yank getting booze to take back and he's very tight (7)
I believe the answer is:
niggard
'tight' is the definition.
(thesaurus)
'yank getting booze to take back' is the wordplay.
'yank' becomes 'drag' (I've seen this before).
'getting booze' becomes 'gin' (I am not sure about this - if you are sure you should believe this answer much more).
'to take back' shows that the letters should be reversed in order (I've seen 'taken back' mean this).
'drag'+'gin'='draggin'
'draggin' backwards is 'NIGGARD'.
'and he's very' is the link.
This may not be correct. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for niggard that I've seen before include "He's tight" , "Mean, stingy person" , "Super-saver" , "Scrooge" , "Mean type" .)
