Routine, over time, included superiority (9)
I believe the answer is:
dominance
'superiority' is the definition.
(thesaurus)
'routine over time included' is the wordplay.
I cannot quite see how this works, but
'over' could be 'o' (cricket abbreviation) and 'o' is located in the answer.
'time' could be 'min' (short for minute) and 'min' is present in the answer.
The remaining letters 'dance' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for dominance that I've seen before include "Ascendancy" , "Power (over others)" , "Mastery" , "Supremacy" , "Commanding position" .)
