I return invoice with time left to be bigoted (9)
I believe the answer is:
illiberal
'bigoted' is the definition.
(I've seen this in another clue)
'i return invoice with time left' is the wordplay.
'return' shows that the letters should be reversed in order.
'invoice' becomes 'bill' (synonyms).
'with' is a charade indicator (letters next to each other).
'time left' becomes 'lare' (I am not sure about this - if you are sure you should believe this answer much more).
'bill' after 'lare' is 'larebill'.
'larebill' backwards is 'lliberal'.
'i'+'lliberal'='ILLIBERAL'
'to be' acts as a link.
Can you help me to learn more?
(Other definitions for illiberal that I've seen before include "Intolerant; reactionary" , "unenlightened?" , "Narrow-minded" , "Reactionary - mean" , "Intolerant; ungenerous" .)
