Steps securing old minister power over others (9)
I believe the answer is:
dominance
'power over others' is the definition.
I can't tell whether this definition defines the answer.
'steps securing old minister' is the wordplay.
'steps' becomes 'dance' ('dance step' can be a synonym of 'step').
'securing' means one lot of letters goes inside another.
'old' becomes 'o' (abbreviation).
'minister' becomes 'min' (abbreviation).
'o'+'min'='omin'
'dance' enclosing 'omin' is 'DOMINANCE'.
Can you help me to learn more?
(Other definitions for dominance that I've seen before include "Power (over others)" , "Supremacy" , "Control - ascendency" , "Influence (over others)" , "Mastery" .)
