The kanji 関 is a phono-semantic compound (形声文字, けいせいもじ). The semantic component (意符, いふ) is 門 (もん), meaning "gate" or "door," which signifies the location. The phonetic component (音符, おんぷ) is 㞷 (かん), which contributes to the pronunciation カン (kan). The character originally depicted a gate with a latch, emphasizing the concept of a barrier or place of passage. Over time, the meaning expanded to encompass the ideas of connection, involvement, and relationship.
