hearse
輀 centers on a vehicle for carrying the dead: a hearse. The meaning is narrow and concrete, with no major abstract extensions.
輀 combines 車 (vehicle) with 而, which likely contributes the sound. The character is rare and its exact historical development is uncertain.
The left side is a vehicle 車, and the right side 而 looks like a draped cloth or a covered shape. Picture a covered cart used as a hearse.
For ジ, imagine a hearse with a giant letter G painted on the side: G -> ジ, and the vehicle carries the coffin.
