Move laterally (5)
I believe the answer is:
sidle
'move laterally' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for sidle that I've seen before include "Edge along furtively" , "sidewalk" , "Slink, creep, sneak" , "Slide (anag.)" , "Move in furtive manner, edge along" .)
