Colonist gets letters sent out (7)
I believe the answer is:
settler
'colonist' is the definition.
(I know that colonist can be written as settler)
'letters sent out' is the wordplay.
'letters' can be anagrammed to 'SETTLER'.
Though, I'm unsure how the anagram is indicated.
'gets' is the link.
Can you help me to learn more?
(Other definitions for settler that I've seen before include "Early mover into an area" , "decisive blow" , "Coloniser - arbitrator" , "Person who moves into an uninhabited country" , "One taking up residence in a new area" .)
