simp. and trad.		刀
alternative forms		𠚣

Pictogram (象形) – a knife. The original form was 𠚣, which can be found in a variant of 利, 𥝢 (in turn used on the top of the character 黎).

Unclear. Here are several proposals:

• Schuessler (2007) considers this to be an area word or a word widely borrowed from Chinese into other languages; compare Proto-Karen *ʔdɔ (“knife”), Jingpho [script needed] (n³¹-do³¹, “short knife”), Proto-Vietic *-taːw (“knife”), Bulo Stieng taaw;
• Stephen Baron posits Proto-Sino-Tibetan *s-ta-w, with a sparsely attested suffix *-w retained in Sinitic yet lost in Tibeto-Burman, yielding Proto-Tibeto-Burman *s-ta (“knife; axe; sword”); compare Tibetan སྟ་རེ (sta re, “axe; hatchet”), Burmese ဓား (dha:, “knife; sword”), Proto-Loloish *ta² (“knife”) (STEDT);
• Starostin derives it from Proto-Sino-Tibetan *tā̆w ~ *dā̆w, comparing it to Tibetan སྟེའུ (ste'u, “carpenter's axe, adze”) and Jingpho nhtu (“sword”).

Alternative spellings

From Old Japanese. First cited to the Nihon Shoki of 720 CE.^[1] From Proto-Japonic *katana.

Compound of 片 (kata, “one side”) + な (na, “edge”).^[2][3][4] This na element is spelled in monolingual Japanese sources as 刃 (“edge, blade”), but there is no historical attestation for any na reading for this character. A comparison with Middle Korean ᄂᆞᆶ〮 (nólh, “blade”) and modern Korean 날 (nal) suggests a Koreanic origin for this latter element.^[5]
