But not too mean to get merry? (5)
I believe the answer is:
tight
This might be a double definition.
'but not too mean' is the first definition.
'tight' can be an answer for 'mean' (both can mean miserly). I'm not certain of the 'but not too' bit.
'merry?' is the second definition.
(both can mean drunk)
'to get' acts as a link.
Can you help me to learn more?
(Other definitions for tight that I've seen before include "Drunk; restricted" , "Drunk - a near thing!" , "Firmly fastened; drunk" , "Mean; tipsy" , "Hard to move; drunk" .)
