One expelled from Spain left, collected by river (8)
I believe the answer is:
deportee
'one expelled' is the definition.
I can't judge whether this defines the answer.
'spain left collected by river' is the wordplay.
'spain' becomes 'e' (abbreviation for Espana).
'left' becomes 'port' (left side of a ship - opposite of starboard).
'collected by' is an insertion indicator.
'river' becomes 'dee' (River Dee).
'e'+'port'='eport'
'eport' placed within 'dee' is 'DEPORTEE'.
'from' is the link.
Can you help me to learn more?
(Other definitions for deportee that I've seen before include "One sent home" , "One ejected" , "Exile" , "Expelled foreigner" , "Person sent back to land of origin" .)
