Conflict is over issue about which steps taken (10)
I believe the answer is:
dissonance
'conflict' is the definition.
(I know that dissonance is a type of conflict)
'is over issue about which steps taken' is the wordplay.
'over' says to put letters next to each other (in a down clue, some letters go over others).
'issue' becomes 'son' (issue can mean someone's offspring).
'about which' indicates putting letters inside (some letters go about or around others).
'steps taken' becomes 'dance' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'is'+'son'='isson'
'isson' put within 'dance' is 'DISSONANCE'.
Can you help me to learn more?
(Other definitions for dissonance that I've seen before include "Harsh sound" , "Clashing quality of musical notes" , "Discordance" , "sounds harsh" , "Lack of harmony" .)
