Adrift, like carrier (6)
I believe the answer is:
astray
I believe this is a double definition.
'adrift' is the first definition.
(I've seen this before)
'like carrier' is the second definition.
(I've seen this before)
(Other definitions for astray that I've seen before include "Missing, lost" , "Off target" , "Adrift - misguided - lost" , "Off the right track" , "Gone off the right path" .)
