An uprising, sure to be crushed, will follow (6)
I believe the answer is:
pursue
'follow' is the definition.
(to pursue is to follow or chase)
'an uprising sure to be crushed will' is the wordplay.
'an uprising' indicates anagramming the letters.
'to' says to put letters next to each other (I've seen this in other clues).
'be crushed will' becomes 'pu' (I can't justify this - if you can you should give a lot more credence to this answer).
'sure' anagrammed gives 'rsue'.
'rsue' put after 'pu' is 'PURSUE'.
Can you help me to learn more?
(Other definitions for pursue that I've seen before include "Give chase" , "Follow, chase" , "Chase, run after" , "Follow up on or go after" , "Dog" .)
