Get a sit-in arranged and use provocation (9)

I believe the answer is:

instigate

I'm a little stuck... Click here to teach me more about this clue!

'get' is the definition.
(I know that instigate is a more specific form of the action get)

'a sit-in arranged and use provocation' is the wordplay.
'arranged' is an anagram indicator.
'and' is a charade indicator (letters next to each other).
'use provocation' becomes 'gate' (I can't explain this - if you can you should believe this answer much more).
'sit'+'in'='sitin'
'sitin' with letters rearranged gives 'insti'.
'insti'+'gate'='INSTIGATE'

Can you help me to learn more?

(Other definitions for instigate that I've seen before include "Prompt" , "Urge on - teasing it (anag)" , "I taste gin to incite or urge" , "Start" , "Urge and bring about" .)

I've seen this clue in The Globe and Mail.
