Some abodes sailors selected in port (6)
I believe the answer is:
odessa
'port' is the definition.
(I've seen this before)
'some abodes sailors selected' is the wordplay.
'some' indicates a hidden word (some of the parts of the word are used).
'ODESSA' can be found hidden inside 'abodes sailors selected'.
'in' is the link.
(Other definitions for odessa that I've seen before include "Ukrainian naval base" , "Ukrainian location" , "Port city of Ukraine" , "Do seas come into Ukrainian city?" , "Black Sea location" .)
