repudiate, exclude, expel, reject, line up, arrange
排 centers on pushing something away or out: repudiating, excluding, expelling, or rejecting. The sense of lining up or arranging comes from the idea of pushing things into order.
排 combines 扌 (hand) with 非, which likely contributes both sound and the idea of negation or opposition, suggesting a hand pushing something away.
A hand 扌 pushing away something wrong 非: imagine using your hand to reject or expel something that is not right.
For ハイ, imagine a hand pushing away a high stack of papers: high -> ハイ, and the hand is arranging them by pushing the unwanted ones aside.
