Drive able to be seen when broadcast (6)
I believe the answer is:
incite
'drive' is the definition.
(I've seen this before)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for incite that I've seen before include "Foment, urge on" , "Provoke - stimulate" , "Prompt" , "Encourage or stir up" , "Stir up (trouble)" .)
