the.com/endnote

means A note placed at the end of a chapter, article, or book that gives sources, citations, or extra comments tied to a specific point in the text.

from Simply built from 'end' plus 'note' — a plain compound coined to distinguish these back-of-the-book notes from 'footnotes,' which sit at the foot of each page. 'Note' itself traces back to Latin 'nota,' a mark or sign used for recording something. The word is modern and functional, not a borrowing or a romantic tale — scholarly publishing just needed a clear label once it became common to shove all the citations to the back rather than scatter them page by page.
