quarrel
鬩 centers on conflict and verbal strife: a quarrel or heated argument between people.
鬩 combines 鬥 (fight, conflict) with 兒 (child), suggesting a quarrel or dispute, possibly originally depicting children fighting. The exact historical development is uncertain.
Inside the fighting enclosure 鬥, picture a child 兒 throwing a tantrum and quarreling loudly. The scene captures the idea of a quarrel.
For ケキ, imagine a quarrel that sounds like a sharp 'keki' noise—like two angry voices clashing: keki -> ケキ.
