Historical forms of the character 武
Shang	Western Zhou	Warring States	Shuowen Jiezi (compiled in Han)	Liushutong (compiled in Ming)
Oracle bone script	Bronze inscriptions	Chu slip and silk script	Small seal script	Transcribed ancient scripts

Ideogrammic compound (會意／会意) : 戈 (“blade”) + 止 (“foot; to walk; to stop”) – army going on an expedition. In the character 武, the 戈 component is written above the 止 component.

The graphical origin of 武 as “to stop violence” — the ultimate state of just warfare — is traditionally attributed to King Zhuang of Chu [597 BCE]:

Linguistically, this was likely a misinterpretation, as 止 always means “to walk” (趾) when used as a radical, compare 步 (bù), 歷／历 (lì) and 歧 (qí).

From Proto-Sino-Tibetan *d-mak (“war, army, soldier”). Cognate with Tibetan དམག (dmag, “army”), Burmese မက် (mak) (as in ရဲမက် (rai:mak, “soldier”) (STEDT; Schuessler, 2007; Sagart, 2017d).
