Reportedly visible urge (6)
I believe the answer is:
incite
'urge' is the definition.
(I've seen this in another clue)
'reportedly visible' is the wordplay.
'reportedly' shows a homophone (sound like).
'visible' becomes 'insight' (something in sight is visible).
'insight' sounds like 'INCITE'.
(Other definitions for incite that I've seen before include "Urge (to violence)" , "Stir up (trouble)" , "Stir up (eg, violence)" , "Stir up, rouse to action" , "drive" .)
