"It" is pronounced /ɪt/, with the short "i" sound as in "bit" and the "t" consonant. Together, "past it" is pronounced /ˈpæst ɪt/ in IPA.
"Past it" is an idiomatic expression that typically refers to someone or something that is no longer capable, effective, or relevant due to advanced age or deterioration. The term can be used to describe both people and objects, indicating that they have outlived their usefulness or lost their prime state.
When used in relation to individuals, "past it" suggests that a person has reached an age or stage in life where they are considered old or no longer able to perform tasks or activities with the same skill, energy, or efficiency as they used to. It implies that their capabilities have declined, and they are no longer as effective or productive as they once were. For example, an athlete who is described as "past it" may no longer possess the physical abilities to compete at the same level as before.
In regards to objects, "past it" implies that an item has deteriorated to the point where it is no longer functional, reliable, or desirable. The object may have become outdated, worn out, or broken, rendering it unfit for its intended purpose. For instance, a piece of machinery that is described as "past it" may be incapable of performing its designated tasks due to long-term wear and tear.
In either case, "past it" conveys a sense of diminished capabilities or quality, often attributed to age or deterioration.
The phrase "past it" is an informal expression commonly used in English to mean that someone or something is too old or worn out to be useful or successful. The word "past" in this context is an adverb meaning "beyond" or "no longer subject to" a particular state or condition.
The origin of this phrase can be traced to the late 19th century and early 20th century, where it first emerged in the realm of sports and specifically horse racing. In horse racing, when a horse has passed its peak performance or prime years, it is said to be "past it" or "past its best". From there, the phrase gradually gained wider usage to mean someone or something that has declined in ability, usefulness, or effectiveness due to age or wear.
