What is break 80 in golf?

Answer 1

It means the player took 89 strokes to complete the stipulated round. Let's hope that was for 18 holes. It could be 89 actual strokes, a stroke defined as "a forward movement of the club with the intent of fairly striking the ball" or some could be penalties for things like losing a ball in a water hazard.

Answer 2

To break 80 you need to get below 80 strokes eg 75, 72, 68

Answer 3

For 18 holes you shoot 89 or less.
