Small issue can create rebellion (8)
I believe the answer is:
sedition
'rebellion' is the definition.
(thesaurus)
'small issue' is the wordplay.
'small' becomes 's' (abbreviation - e.g. clothes size).
'issue' becomes 'edition' (edition is a kind of issue).
's'+'edition'='SEDITION'
'can create' is the link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for sedition that I've seen before include "Revolting behaviour" , "Actions promoting disorder" , "Subversive activity" , "Action inciting rebellion" , "Rabble-rousing" .)
