The kanji 何 primarily means "what," "which," or "how." It is used to ask questions, inquire about something, or indicate uncertainty. It signifies a lack of specific knowledge or a desire for information. It can also imply "something" or "anything" in certain contexts.

The kanji 何 is a phono-semantic compound. The left side is the radical of 人(jin/hito: person), and the right side is the phonetic component 可(ka: can, may). The original meaning related to "people". Over time, it came to be used to express questioning, thus evolving into its modern meaning of "what" or "how."
