Miserly type drunk on whisky and Drambuie, principally (8)
I believe the answer is:
tightwad
'miserly type' is the definition.
(a tightwad is a miserly person)
'drunk on whisky and drambuie principally' is the wordplay.
'drunk' becomes 'tight' (slang term).
'on' says to put letters next to each other.
'principally' suggests taking the first letters.
The first letters of 'whisky and drambuie' is 'wad'.
'tight'+'wad'='TIGHTWAD'
(Other definitions for tightwad that I've seen before include "Miserly person" , "Miser (sl.)" , "Cheapskate" , "Mean person (US)" , "Skinflint" .)
