Comprehensive resource for understanding and mastering English idioms
The idiom "lose head" is used to describe a sudden feeling of shock, disbelief, or confusion that can be so overwhelming that someone loses their composure and sense of reality. The phrase itself is derived from the idea of losing one's physical head, which symbolizes the loss of all control and awareness.
"Lose head" means to feel stunned, overwhelmed, or bewildered, often to the point where someone loses their composure and ability to think rationally.
The origin of the idiom "lose head" dates back to medieval times when soldiers would sometimes wear helmets with a cage-like structure that protected their heads. These cages were often used in battle, where soldiers could quickly don them if they sensed danger coming from all sides. However, if the soldier lost his head in the midst of a fight, the cage would remain empty, making it look like he had literally lost his head. Over time, the idiom "lose head" has evolved to mean something more metaphorical than losing one's physical head. It now refers to a sudden feeling of shock or confusion that can be so overwhelming that someone loses their sense of reality and control.
