Usage

What’s the difference between a footnote and an endnote? A footnote is a note at the bottom (the “foot”) of a page. An endnote is a note at the end of a text (such as an article, a chapter, or an entire book). The difference between footnotes and endnotes is their location, not their function. Both consist of information added to a text in another spot, such as an explanation or a citation of a source. They are both usually indicated with some kind of mark, often an asterisk* or a number¹. The same mark appears in another part of the text along with the corresponding note, either at the bottom of the page (making it a footnote) or at the end of the text (making it an endnote). Of course, if an article is only a single page, the note at the end could be called a footnote or an endnote. Here’s an example of footnote and endnote used correctly in the same sentence. Example: I use footnotes for tangential information so that readers can access it without turning the page, but I use endnotes for citations so they don’t clutter up the page. Want to learn more?

Explanation

A footnote is a short bit of extra information that's printed at the bottom of a book's page. Some footnotes cite the authors and titles of the sources the author consulted while researching and writing. The presence of footnotes usually means you're reading an academic or scholarly work of nonfiction. Your history paper might include footnotes on each page, noting the books, journals, and websites you used for your research. Some contemporary novels have footnotes as well, a complex and playful way for the author to insert extra notes and details. The foot of a page is the bottom, which explains the word footnote.
