The kanji 許 is a phono-semantic compound (形声文字, けいせいもじ). The left side of the character is 言（ことば, kotoba), meaning "words" or "speech," which serves as the semantic component, indicating that the meaning of the character is related to something verbal or concerning permission. The right side of the character is 午（うま, uma), which is a phonetic component, originally representing a horse. The combination of these elements created 許, originally implying giving permission or allowing by speech (the semantic component). Over time, the meaning broadened to encompass forgiveness, tolerance, and other related concepts.
