側そばむ

godan verb (-mu), intransitive verb

lean to one side; oppose; look aside; regret

Rare archaic verb. The core image is turning or leaning away from something, giving rise to the extended meanings of opposing, looking away, and regretting. Modern Japanese uses 傾く, 反対する, 横を見る, 後悔する instead.

• 古こ語ごでは「そばむ」は「かたむく」や「そむく」の意いで使つかわれた。

  In classical Japanese, そばむ was used to mean 'to lean' or 'to oppose'.
