Break point, set point and match point
Distinguish a chance to win a return game from an opportunity to finish the set or the match.
An opportunity is not an outcome
These phrases tell you what the next point could achieve, not what has already happened. A player can have several chances and convert none. A scoreboard is easier to read when opportunity and result stay separate.
In a standard game, break point is a point on which the receiver could win the game. A hypothetical receiver leading 40-30 could take the server's game next. If the server wins that point, the score returns to deuce.
Set and match points add more layers
A set point is an opportunity to win the set next. It can happen on serve or return. In a hypothetical standard set, a server leading 5-4 and 40-30 could finish the set by winning the next point. A game point at 2-2 does not have that consequence.
A match point can finish the entire match. Completed sets and match format decide whether a set-ending point is also match-ending. A current point score alone cannot answer that.
One point can have several labels
A receiver could face a point that wins the return game, the set and the match together. That point can be both break point and match point. The phrases describe different levels of the same opportunity.
Three break-point chances do not mean three breaks of serve. Conversion is a separate outcome. Saving match points is not a victory until the remaining match has been won.
