milwort
蕀 is a rare kanji for a specific plant, milwort. Its meaning is narrow and botanical, with no clear abstract extensions.
蕀 combines the grass radical 艹 with 棘 (thorny bush), likely indicating a thorny or spiny plant. The exact historical development is uncertain.
The top grass radical 艹 sits above 棘, a thorny bush. Picture a low-growing milwort plant with tiny thorn-like leaves among the grass.
For キョク, imagine a milwort plant growing in a crooked shape: 'kyoku' sounds like a bent, twisted stem, and the plant's thorny nature makes it look crooked.
