Type of force exhibited by ruler in revolutionary territory (9)
I believe the answer is:
resultant
'type of force exhibited' is the definition.
I can't judge whether this defines the answer.
'ruler in revolutionary territory' is the wordplay.
'ruler' becomes 'sultan' (sultan is a kind of ruler).
'in' means one lot of letters goes inside another.
'revolutionary' is a reversal indicator (letters revolve around).
'territory' becomes 'ter' (I've seen this in other clues).
'ter' written backwards gives 'ret'.
'sultan' placed inside 'ret' is 'RESULTANT'.
'by' is the link.
Can you help me to learn more?
(Other definitions for resultant that I've seen before include "Ensuing, consequent" , "force" .)
