Current import (5)
I believe the answer is:
drift
I believe this is a double definition.
'current' is the first definition.
(can be similar in meaning in navigation contexts)
'import' is the second definition.
(thesaurus)
(Other definitions for drift that I've seen before include "Stray" , "General trend - current travel" , "Be slowly carried by a current" , "aimless" , "Float with current" .)
