Pause in indecision (8)
I believe the answer is:
hesitate
'pause in indecision' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for hesitate that I've seen before include "Do this perhaps to be lost" , "Be uncertain about decision" , "'Pause, dither (8)'" , "Dither, waver" , "Arrangements of units that function together" .)
