I'm to get the beer he brings into the country (8)
I believe the answer is:
importer
'he brings into the country' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'i'm to get the beer' is the wordplay.
'to get' is a charade indicator (letters next to each other).
'the beer' becomes 'porter' (type of beer).
'im'+'porter'='IMPORTER'
Can you help me to learn more?
(Other definitions for importer that I've seen before include "One buys in" , "A trader in foreign goods" , "One bringing in goods to country" , "Foreign dealer" , "Businessperson" .)
