quarrel, dispute
奻 centers on conflict between people: a quarrel or dispute. The meaning is narrow and concrete, focused on verbal or interpersonal strife.
奻 is composed of two 女 (woman) elements side by side. The exact historical origin is uncertain, but the duplication likely suggests conflict or rivalry.
Two women (女) standing side by side, arguing fiercely. Their identical shapes mirror each other, like two sides of a dispute.
For ダン, imagine the two women in a heated debate, and one shouts 'Done!' to end the quarrel: done -> ダン.
