The word "madcap" emerged in Middle English around the 14th century, and its etymology can be broken down into two components: "mad" and "cap".
The term "mad", derived from Old English "gemǣdde", originally meant "insane" or "mentally unsound". Over time, it evolved to also denote extraordinary excitement or enthusiasm.
On the other hand, "cap" refers to a hat. In medieval times, jesters or fools were known for wearing caps adorned with bells and decorated in a whimsical manner. These caps became emblematic of their unconventional and reckless behavior.
Combining the words "mad" and "cap" resulted in the term "madcap", which eventually came to describe someone who is impulsive, reckless, or unconventional in their actions, often associated with a sense of adventure or excitement.
