Semantic Clue (形旁):辶 (indicates movement or traveling)

卂 flying fast
5. History
Liushu category: Phono-semantic (形声)
Origin: Originally depicted by a bird flying fast (卂) combined later with the walking radical (辶) to emphasize swift travel and speed.
Semantic Evolution: Shifted from literal flying speed to general concepts of rapidity, quickness, and promptness in modern Mandarin.
In classical texts, 卂 alone carried the sense of flying fast, which later required the addition of the movement radical 辶 for clarity.

Clue: xùn sù
Common Learner Pitfall
Mistaking 迅 for 讯 because they share the exact same pronunciation and tone, leading to incorrect usage in compounds like 通讯 vs. 通迅 (the latter being wrong).
Memory Prompts
