stop
跱 centers on stopping or coming to a halt, especially in the context of movement or travel.
跱 combines 足 (foot) with 寺, which likely contributes the sound. The exact historical development is uncertain, but the structure suggests a phono-semantic compound related to stopping movement.
The left side is 足 (foot), and the right side is 寺 (temple). Imagine a foot stopping at a temple gate, pausing the journey.
For チ, picture a foot stopping right at the entrance of a cheese shop: cheese -> チ, and the foot halts before going in.
