轍

Concrete: Physical impressions in the earth; can emphasize either the trace (evidence of passage) or the groove (the depression itself).

Figurative: Precedent and ingrained paths. Implies a trajectory worn into the earth over time, suggesting a legacy to be followed or a constraint/habit that creates a narrow, inevitable trajectory (contrasting with the expansive nature of 道).

Primarily functions as a noun. In verbal positions, look for an implied verb of motion (leaving a track) or adherence (following a rut).

vs. 軌 (guǐ): While both involve wheels/tracks, 軌 typically refers to the gauge (distance between wheels) and leans toward standards or rules; 轍 is the physical, lived result of travel.

vs. 跡 (jì): 跡 refers to a footprint or ephemeral trace; 轍 implies a deeper, structural indentation.

vs. 路 (lù): 路 is a road or destination-oriented path; 轍 is the specific indentation within that road.

Simplified variant: U+8F99. Fanqie reading: 直列; Tang-period reading: djhiɛt.
