Gesture to follow (6)
I believe the answer is:
beckon
'gesture to follow' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for beckon that I've seen before include "Summon with finger gesture" , "Summon with gesture (6)" , "Make signs to summon" , "Summon by gesturing" , "Gesture closer" .)
