Cut further beer and spirits (6)
I believe the answer is:
morale
'spirits' is the definition.
(thesaurus)
'cut further beer' is the wordplay.
'cut' means to remove the last letter.
'further' becomes 'more' ('more' can be a synonym of 'further').
'beer' becomes 'ale' (I've seen this before).
'more' with its last letter removed is 'mor'.
'mor'+'ale'='MORALE'
'and' is the link.
(Other definitions for morale that I've seen before include "State of mental confidence" , "General level of confidence or optimism" , "Strength of purpose" , "Spirits" , "The spirit of a group or individual" .)
