skin, tell, report
臚 centers on the skin as a surface that reveals or communicates: telling or reporting something outwardly. The meanings 'skin' and 'tell/report' connect through the idea of making something visible or known on the surface.
臚 combines ⺼ (flesh, body part) with 盧, which likely contributes the sound. The character originally referred to the skin or surface of the body, and later extended to the idea of displaying or reporting something outwardly.
The left side ⺼ (flesh) suggests the body, and the right side 盧 looks like a complex container. Imagine the skin as the container of the body that tells its story on the surface—every scar or blush reports something.
For ロ, picture a low, rumbling report coming from the skin: low -> ロ, as if the skin itself is murmuring a secret.
