无

It literally means "to not have" or "to be without".

It is the ancient form of the character 無, representing the concept of non-existence or absence of something. In China, 无 is used as the simplified form of 無.

The exact origin is unknown, and its meaning is believed to have been assigned due to its phonetic similarity to "없을 무" (meaning "not exist").

This radical is extremely rare.

In many non-Korean Chinese character dictionaries, the radical is excluded entirely due to its limited usage.

In some Japanese dictionaries, it is merged under the 牙 (tooth) radical.

In some Chinese dictionaries, the 无 radical (a simplified form of 旡) is omitted or reclassified.

This radical is mainly of historical interest and rarely encountered in modern usage.

As a radical, it includes the character 旡 (목멜 기, "to choke" or "to be unable to breathe"), which closely resembles 无.

Visually, it resembles the character for "sky" (天).
