Unmoored (6)
I believe the answer is:
adrift
'unmoored' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for adrift that I've seen before include "Disoriented" , "Floating freely, not moored" , "(Of ship) out of control" , "(Of boat) moving out of control" , "out of touch" .)
