Lacrosse score (4)
I believe the answer is:
goal
'lacrosse score' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for goal that I've seen before include "could be worth 3 points" , "Objective or score" , "Object of one's ambition" , "Aim - striker's target" , "Crossbar, posts and nets" .)
