Stingy individual back on cheaper booze (4)
I believe the answer is:
beer
'booze' is the definition.
'stingy individual back on cheaper' is the wordplay.
'stingy individual' becomes 'bee' (I am not sure about this - if you are sure you should believe this answer much more).
'back on' says to take the final letters (the letter at the back).
The final letter of 'cheaper' is 'r'.
'bee'+'r'='BEER'
Can you help me to learn more?
(Other definitions for beer that I've seen before include "Brewery product" , "Fermented alcoholic beverage" , "See 4 down" , "Perhaps bitter" , "Drink with a head" .)
