Conclusion
The idiom "flat out" has three main meanings, all related to aspects of speed, effort, or exhaustion. The first meaning is to do something at maximum or full speed, often in a physical sense. This can refer to working hard, running or moving quickly, or acting with great intensity. The second meaning is to do something completely or entirely, without holding back. This could refer to giving something your all, being completely committed, or leaving nothing undone. The third meaning is to be completely exhausted or worn out, usually from physical activity. This can also be used to describe a state of being completely spent or drained, mentally or emotionally.Origin of "Flat out"
The origin of the idiom "flat out" is thought to come from the literal meaning of the phrase, which dates back to around the 1500s. Originally, it was used to describe something that was completely flat, without any curves or bumps. Over time, the phrase was also used to describe something that was done with great speed and intensity, as if moving in a straight line. This evolved into the modern meaning of "working at full speed" or "giving your all."
Another theory suggests that the idiom may have originated from horse racing, where horses would run "flat out" or at their maximum speed on a flat track. This usage then transferred to other activities and tasks that require maximum effort or speed.
Some examples of the idiom "flat out" in use can be found in literature and media, such as in Mark Twain's "The Adventures of Huckleberry Finn" where the character Huck says, "We said there warn't no home like a raft, after all. Other places do seem so cramped up and smothery, but a raft don't. You feel mighty free and easy and comfortable on a raft." This could be interpreted as the second meaning of "completely or entirely." In modern times, the idiom is used in a variety of contexts, from describing someone who is working "flat out" on a project to someone who is "flat out" exhausted after a long day.
