to walk alone, self-reliant
踽 centers on walking alone, emphasizing solitude and self-reliance in one's path.
踽 combines 足 (foot) with 禹, which likely contributes the sound. The character expresses walking alone, with 足 indicating movement.
The left side 足 means foot, and the right side 禹 looks like a solitary figure with a staff. Picture a lone traveler walking step by step, self-reliant on the road.
For ク, imagine a cool, solitary walk under the moon: cool -> ク, and you walk alone.
