Definition of the word toe

The origin of the word "toe" is Old English, and it is closely related to the word "tone," which refers to the smallest part or unit of something. In this case, a "toe" is the smallest unit of the human foot. The Old English word "tō" or "tōh" likely originated from Proto-Germanic "*tüzziz," which was also the source of the Modern German word "Zeh," meaning toe. The word "toe" has been a part of the English language since the 9th century and has remained relatively unchanged over time. In Middle English (circa 1100-1500), the word was spelled "to," and it wasn't until the 15th century that it became standard to use the modern spelling "toe." Today, the word "toe" is used to refer to any of the five digits at the end of the human foot, as well as in idioms and expressions, such as "toe the line" and "hold someone's toe to the fire."
