Move, flow (4)
I believe the answer is:
pass
I believe this is a double definition.
'move' is the first definition.
(I know that pass is a type of move)
'flow' is the second definition.
(thesaurus)
(Other definitions for pass that I've seen before include "Mountain route; come to an end" , "Transfer" , "At Wembley, no shot" , "Search me" , "degree?" .)
