duel

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

'fight' is the definition.
(I know that duel is a type of fight)

'outstanding lawyers primarily' is the wordplay.
'outstanding' becomes 'due' (an outstanding debt is due).
'primarily' says to take the initial letters.
The initial letter of 'lawyers' is 'l'.
'due'+'l'='DUEL'

'between two' is the link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.

Can you help me to learn more?

(Other definitions for duel that I've seen before include "Fight over a point of honour" , "shoot-out?" , "Fight between two persons" , "Two-person combat" , "Gentlemen's disagreement" .)
