Recognition or thanks given to people who helped with a project, book, or research; the plural of acknowledgement.
From Middle English 'knowlechen' meaning 'to admit or recognize,' combined with the suffix '-ment' (state or result). The word evolved from Old English roots meaning 'to know' and eventually came to mean formal recognition.
Authors hide Easter eggs in acknowledgements sections—you'll find jokes, cryptic thanks to people who inspired fictional characters, and sometimes even dedications to pets that sat on their keyboards, making it the most personal page in a book.
