goalpost

The word 'goalpost' is a transparent compound formed from two native English elements. 'Goal' originally signified a boundary or limit, a concept fundamental to defining the endpoint in a race or contest. 'Post' derives from the Latin 'postis', referring to an upright beam or pillar, a common structural element. Their combination in the 16th century created a literal descriptor for the physical structure marking the scoring area in sports. The modern figurative sense, "moving the goalposts," emerged in the mid-20th century, extending the sports metaphor to describe the unfair alteration of agreed-upon rules or targets during an endeavor.
