out on one’s feet: Idiom Meaning and Origin

The idiom "out on one's feet" is commonly used in American English to describe someone who is physically or mentally exhausted, to the point where they can barely function. The origins of this idiom can be traced back to the early 20th century, but its exact origins are unclear.

One theory suggests that the idiom may have originated from the sport of boxing, where the term "knockout" is commonly used. When a boxer is knocked out, they are unable to continue the fight, often falling to the ground and needing assistance to stand up. This correlation between being unable to stand and being completely exhausted could have given rise to the idiom "out on one's feet". However, there is no definitive evidence to support this theory.

Another possible origin of this idiom could be related to the phrase "knock someone off their feet". This phrase means to surprise or impress someone greatly. It is possible that "out on one's feet" developed as an extension of this phrase, suggesting that someone is so tired that they are completely taken aback and unable to function properly.

The unique combination of the words "out" and "feet" in this idiom creates a vivid image of someone who is so tired that they can no longer stand or walk properly.
