Definition of footnote

The term "footnote" originated in the 16th century, likely from the practice of writing notes at the bottom (foot) of a page. The earliest recorded use of the word "footnote" is in the 1590s. While the concept of adding explanatory notes to text existed long before this, the specific term "footnote" emerged as a way to describe this practice, reflecting the physical location of the notes on the page. The word has evolved over time, but its core meaning—a note at the bottom of a page—remains consistent.
