strong, unyielding, forceful
逎 centers on strength that does not bend: being unyielding, forceful, or pressing forward with intensity.
逎 combines 辶 (movement) with 酉, which likely contributes the sound and may relate to pressing or maturing, but the exact historical development is uncertain.
The movement radical 辶 surrounds 酉, like a forceful advance pressing in on a wine vessel. Imagine an unstoppable force closing in, strong and unyielding.
For シュウ, picture a strong shoe pressing forward: shoe -> シュウ, and the forceful movement matches the kanji's meaning.
