hermitage
廬 centers on a simple, rustic dwelling used for retreat or seclusion: a hermitage or small hut away from everyday life.
廬 combines 广 (building with a roof) and 盧, which likely contributes the sound and may relate to a dwelling or hut. The character originally referred to a simple temporary shelter or hermitage.
Under a broad roof 广, the dense inner shape 盧 suggests a rustic, hand-built shelter. Picture a simple hut tucked away in the mountains: a hermitage.
For ロ, imagine a low, humble hermitage with a low roof: low -> ロ, and the low roof shelters the hermit.
