Getting drunk is difficult on such a budget (5)
I believe the answer is:
tight
'getting drunk' is the definition.
'tight' can be an answer for 'drunk' (I've seen this before). I am not sure about the 'getting' bit.
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for tight that I've seen before include "Bottled ," , "unlikely to come loose" , "Closely fought game" , "reluctant to buy a round?" , "Closely constrained, constricted" .)
