Goods brought in one Frenchman left at sea (6)
I believe the answer is:
import
'goods' is the definition.
(import is a kind of goods)
'one frenchman left at sea' is the wordplay.
'one' becomes 'I' (Roman numeral).
'frenchman' becomes 'm' (abbreviation for Monsieur - like 'Mr').
'left at sea' becomes 'port' (I've seen this in another clue).
'i'+'m'+'port'='IMPORT'
'brought in' acts as a link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for import that I've seen before include "Bring in; significance" , "Meaning - bring goods into the country" , "introduce" , "Bring in goods from abroad" , "Bring in from abroad to sell" .)
