Definition of the word nuts

The word "nuts" has a fascinating history, rooted in the Old English word "hnotu." This word referred to the edible fruit of certain trees, essentially what we now call nuts. Over time, "hnotu" evolved into "nut" and later "nuts," acquiring a broader meaning to include both edible nuts and, by the 16th century, anything considered "small and hard," like a bolt or a small seed. The term "nuts" as a slang term for "crazy" or "foolish" emerged in the 19th century, likely stemming from the idea of being "out of your mind" or "off your nut." This slang usage, while seemingly unrelated to the original meaning, is a testament to the evolving nature of language.
