goalpost

Imagine a soccer or football field. A goalpost is one of the upright posts that marks the goal, the place where points are scored. In plain use, it means the real post on the field. In everyday speech, though, people often know it from the phrase "move the goalposts," which means to change the rules or the standard after things have already started.

The idea comes from sports, but people use it in work, school, and arguments too. If your boss says you need to sell ten items this week, and then, after you've sold nine, says you now need to sell fifteen, they have moved the goalposts. The phrase usually suggests that the change is unfair.

The word "goalpost" first means one of the upright posts that form part of a goal in sports such as soccer, rugby, and American football. It is a concrete object on the field that helps show where a team must send the ball to score. In this literal sense, the meaning is simple and physical.

From that sports image, the word also appears in figurative language. The most common example is the phrase "moving the goalposts." When someone moves the goalposts, they change the rules, demands, or standard of success after another person has already begun trying to meet them. This often feels unfair because the target was clear at first and then suddenly shifts.

For example, you might agree to finish a project by Friday, and then your manager adds new tasks on Thursday without giving you more time. Or you may meet the terms of a deal, only to hear that new conditions have been added at the last minute. In cases like these, people say the goalposts have been moved.

So the word can point either to the actual post used in sports or, more broadly, to the idea of a target or standard. In everyday English, the figurative use is common, but the basic literal meaning still comes first.
