conjecture, infer, guess, suppose, support, push (for)
推 centers on moving something forward with mental or physical force: pushing an idea, inferring a conclusion, or supporting a cause. The conjecture and guess senses are natural extensions of mentally pushing toward a likely answer.
推 combines 扌 (hand) with 隹, which likely contributes the sound and the idea of pushing or advancing. The character originally expressed physically pushing something forward, later extending to mental inference and support.
A hand 扌 beside a bird-like shape 隹: imagine using your hand to push a bird forward, urging it to fly. That pushing action extends to pushing ideas, inferring, and supporting.
For スイ, picture pushing a swing: swing -> スイ, and your hand pushes the swing forward.
