distant
遼 centers on great distance or remoteness, often in a spatial or temporal sense. The single given meaning 'distant' captures this core idea directly.
遼 combines the movement radical 辶 with 尞, which likely contributes the sound. The character expresses distance or far-reaching movement.
The movement radical 辶 suggests traveling a long path, and the inner component 尞 looks like a distant, hazy landscape with a sun 日 and scattered elements. Together they paint a picture of a far-off journey.
For リョウ, imagine a distant land called 'Ryo' (like a shortened 'Rio'), and you must travel far to reach it: Ryo -> リョウ, and the journey is long.
