The kanji ［斥］ is a 形声文字 (keisei moji), a phono-semantic compound. It combines a phonetic component and a semantic component. The phonetic component is 斤 (kin, meaning "axe" or "weight") which provides the sound of the kanji. The semantic component could be considered 斤 itself, but also implies something related to "to weigh." The meaning of ［斥］ originally related to "to measure," as in "to weigh" or "to examine." Over time, the meaning evolved to its current sense of "to repel," "to reject," or "to exclude." Thus, the character initially was used in a context of assessment, later shifting to a more forceful act of rejecting.
