Published correspondence for remote settlement (7)
I believe the answer is:
outpost
'remote settlement' is the definition.
(I've seen this in another clue)
'published correspondence' is the wordplay.
'published' becomes 'out' (I've seen this in another clue).
'correspondence' becomes 'post' (I've seen this in other clues).
'out'+'post'='OUTPOST'
'for' acts as a link.
(Other definitions for outpost that I've seen before include "Remote place" , "Small group of soldiers" , "Distant part (of empire)" , "settlement difficult to reach?" , "Remote part of the country" .)
