Phono-semantic compound (形聲 /形声, OC *tjeŋ, *tjeŋs): phonetic 丁 (OC *rteːŋ, *teːŋ) + semantic 止 (“foot”) – to go on a long journey. Original form of 征 (OC *tjeŋ, “to go on long campaign”).
Later, 丁 was simplified into a horizontal stroke, as in 旦. Folk etymologies do not recognize 丁. Graphically, the modern version of the character is the reverse of 之.
Sino-Tibetan or area word: “centre; target; first (month); straight; correct”.
Compare Mizo dîng (“to go straight or direct (as person, arrow etc.); to go straight through without breaking the journey; straight; direct”). Matisoff sets up Proto-Sino-Tibetan *m-tjak/ŋ ~ tik/ŋ (“good; very; real; straight”) for this, which includes 正, 直 (OC *dɯɡ, “straight; right”) and 實 (OC *ɦliɡ, “solid; true”).
Additionally, Matisoff has Proto-Sino-Tibetan *t(r)waŋ (“straight; straighten”), whence Chepang धेङ्सा (dʰeŋ-, “straight”), Jingpho ding (“straight”), Tibetan དྲང་པོ (drang po, “straight; correct; upright; just; fair”), Burmese တန်း (tan:, “straight; to head straight for”). Also compare Khmer ទៀង (tiĕng, “accurate; correct; exact; precise; honest”) and Thai ดิ่ง (dìng, “vertically; straight; to plummet”).
Derivatives:
* 征 (OC *tjeŋ, “to go straight > to go on a journey”)
* 政 (OC *tjeŋs, “correct; to govern; government; to determine”)
* 整 (OC *tjeŋʔ, “orderly; to arrange; to dispose”)
