lines
腡 centers on lines, likely referring to linear marks or patterns on the body. Its standalone meaning is narrow and rare.
腡 combines the flesh radical ⺼ with the phonetic component 咼, suggesting a body-related word with a reading derived from 咼. The exact historical development is uncertain.
The flesh radical ⺼ hints at the body. Imagine lines drawn on the skin, like a pattern of stripes or marks.
For ラ, picture a line of la-la-la singing voices tracing lines across the body: la -> ラ.
