I believe the answer is:

set to

I'm a little stuck... Click here to teach me more about this clue!

'conflict' is the definition.
(set-to is a kind of conflict)

'in group over head relinquishing power' is the wordplay.
'in group' becomes 'set' (both can mean a collection. I am not sure about the 'in' bit.).
'over' says to put letters next to each other (in a down clue, some letters go over others).
'head' becomes 'top' (synonyms).
'relinquishing' is a deletion indicator.
'power' becomes 'p' (symbol in physics).
'top' with 'p' removed is 'to'.
'set'+'to'='SET-TO'

Can you help me to learn more?

(Other definitions for set to that I've seen before include "Ding-dong" , "began working" , "Begin" , "Spat" , "closed" .)
