Drag along a path (5)
I believe the answer is:
trail
I believe this is a double definition.
'drag along' is the first definition.
(thesaurus)
'a path' is the second definition.
(trail is a kind of path)
(Other definitions for trail that I've seen before include "Fall behind" , "Way" , "Dog - track" , "Be drawn belong behind" , "Track or scent used in following someone" .)
