正

As a component of some complex characters, 正 is often written as 𤴓 with its last two strokes different. Compare 昰 and 是.

正 (Kangxi radical 77, 止+1, 5 strokes, cangjie input 一卜中一 (MYLM), four-corner 1010₁, composition ⿱一止)

1. Shuowen Jiezi radical №31

• (tally marks, 5): The successive strokes of 正 () are used in China, Taiwan, Japan, Korea and other areas where Chinese characters are prominent to designate tallies in votes, scores, points, sushi orders, and the like, much as is used in Africa, the Americas, Australia, and Europe. Tallies beyond five are written with a 正 for each group of five, followed by the remainder. For example, a tally of twelve is written as 正正丅.

Historical forms of the character 正
Shang	Western Zhou	Shuowen Jiezi (compiled in Han)	Liushutong (compiled in Ming)
Oracle bone script	Bronze inscriptions	Small seal script	Transcribed ancient scripts

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”).

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”).

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”)
