International trader’s former carrier (8)
I believe the answer is:
exporter
'international trader's' is the definition.
'exporter' can be an answer for 'trader's' (I've seen this before). I'm unsure of the 'international' bit.
'former carrier' is the wordplay.
'former' becomes 'ex' (prefix meaning former or onetime).
'carrier' becomes 'porter'.
'ex'+'porter'='EXPORTER'
Can you help me to learn more?
(Other definitions for exporter that I've seen before include "Business that sells its goods abroad" , "One sending goods abroad" , "one sells abroad" , "One selling abroad" , "One making foreign sales" .)
