Drink a lot, taking leak behind back of pub (5)
I believe the answer is:
booze
'drink a lot' is the definition.
'booze' can be an answer for 'drink' (synonyms). I'm not sure about the 'a lot' bit.
'leak behind back of pub' is the wordplay.
'leak' becomes 'ooze' (I've seen this in another clue).
'behind' says to put letters next to each other.
'back of' says to take the final letters.
The last letter of 'pub' is 'b'.
'ooze' after 'b' is 'BOOZE'.
'taking' is the link.
Can you help me to learn more?
(Other definitions for booze that I've seen before include "Consume alcohol" , "plonk?" , "Alcoholic liquor" , "Alcoholic drinks (colloq.)" , "intoxicating stuff" .)
