approach, near, close
迩 centers on physical or relational closeness: approaching, being near, or drawing close to something.
迩 combines the movement radical 辶 with 尔, which likely contributes a phonetic element. The character expresses the idea of moving toward or being near.
The movement enclosure 辶 surrounds 尔, like a path drawing something closer. Picture walking along a road that brings you near your destination.
For ジ, imagine a jeep approaching along the road: jeep -> ジ, and the jeep draws near.
