Definition of numb

The word "numb" originated in the late Middle English period, around the 15th century. Its origin can be traced back to the Old English word "numm" which means insensibility or senselessness. The Old English word "numm" is believed to have come from the Proto-Germanic "mumnaz" which in turn is derived from the Proto-Indo-European root "men" meaning to close or shut. In Middle English, the word "numm" took on the meaning of being insensible or senseless, not just physically but also mentally or emotionally. This meaning continued with the modern English word "numb." In modern English, "numb" is used to describe a physical state of insensitivity or lack of feeling in a specific part of the body, commonly caused by injury, illness, or anesthesia. It can also be used figuratively to describe a lack of emotion or interest in a situation. Its versatility in meaning has allowed it to remain a useful term in the English language for over five hundred years.
