I am left with purchase from abroad (6)
I believe the answer is:
import
'purchase from abroad' is the definition.
I can't tell whether this definition defines the answer.
'i am left' is the wordplay.
'i am' becomes 'I'm' (contraction).
'left' becomes 'port' (left side of a ship - opposite of starboard).
'im'+'port'='IMPORT'
'with' acts as a link.
Can you help me to learn more?
(Other definitions for import that I've seen before include "Bring in from abroad to sell" , "Drift" , "Item from abroad" , "Bring in; significance" , "Meaning - bring goods into the country" .)
