European tax detailed before check (5)
I believe the answer is:
dutch
'european' is the definition.
(I've seen this before)
'tax detailed before check' is the wordplay.
'tax' becomes 'duty' (duty can mean a tax or toll).
'detailed' means to remove the last letter (the word must be end-less or 'de-tailed').
'before' means one lot of letters go next to another.
'check' becomes 'ch' (abbreviation).
'duty' with its last letter removed is 'dut'.
'dut'+'ch'='DUTCH'
(Other definitions for dutch that I've seen before include "& 7 Alcohol-induced nerve" , "People of the Netherlands" , "Netherlandish language" , "mate?" , "Like some cheese" .)
