Man involved in province's uprising (4)
I believe the answer is:
ivor
'man' is the definition.
(I've seen this before)
'involved in province's uprising' is the wordplay.
'involved in' says the answer is hidden in the clue.
'uprising' shows that the letters should be reversed in order.
'rovi' is hidden in the letters of 'provinces'.
'rovi' written backwards gives 'IVOR'.
(Other definitions for ivor that I've seen before include "--- Gurney, Novello" , "- Novello, actor/composer (We'll gather lilacs)" , "Cutler who was entertainingly eccentric" , "__ Novello, Welsh composer and songwriter, d. 1951" , "Man's name" .)
