stagger, falter
踉 centers on unsteady, stumbling movement: staggering or faltering when walking.
踉 combines 足 (foot) with 良, which likely contributes the sound. The character expresses unsteady foot movement.
The left side 足 means foot, and the right side 良 suggests good. Imagine a foot that is supposed to be good but instead staggers and falters.
For ロウ, picture a staggering person trying to walk in a row: row -> ロウ, but their feet keep faltering.
