International trader, former doorman (8)
I believe the answer is:
exporter
'international trader' is the definition.
'exporter' can be an answer for 'trader' (I've seen this before). I'm not sure about the 'international' bit.
'former doorman' is the wordplay.
'former' becomes 'ex'.
'doorman' becomes 'porter' (synonyms).
'ex'+'porter'='EXPORTER'
Can you help me to learn more?
(Other definitions for exporter that I've seen before include "one sells abroad" , "trading abroad" , "Business that sells its goods abroad" , "Overseas trader" , "One sending goods abroad" .)
