Points

From TF2 Wiki

Points are the basic scoring unit of Team Fortress 2, points are awarded for different successful offensive and defensive actions. Performing these actions will also often earn a voice response from the class you are playing.

Points can be given in halves. However, they do not show on your score until you accumulate the other half.

'Point' may also refer to a Control point.
