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.
