Old fortified wine for sale abroad (6)
I believe the answer is:
export
'sale abroad' is the definition.
I can't tell whether this definition defines the answer.
'old fortified wine' is the wordplay.
'old' becomes 'ex'.
'fortified wine' becomes 'port' (port is a kind of fortified wine**).
'ex'+'port'='EXPORT'
'for' acts as a link.
Can you help me to learn more?
(Other definitions for export that I've seen before include "Send (goods) overseas" , "Item sent abroad" , "Sell or transfer abroad" , "Dispose of to another country" , "Sell or give to another country" .)
