Wanders off course (6)
I believe the answer is:
strays
'wanders off course' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for strays that I've seen before include "Wanders off course" , "Wanders off the path, gets lost" , "Wanders off, digresses" , "Wanders off with satyrs" , "Wanders off the right path" .)
