The kanji 某 is a 形声文字 (keisei moji), a phono-semantic compound. The phonetic component is 莫 (baku/maku), meaning "not" or "none." The semantic component is a 木 (ki), meaning "tree" or a symbol representing something. The original meaning might have been related to a specific unknown tree or location. Over time, it developed the meaning of "some" or "unspecified," borrowing the sound of 莫.
