すみ

From Old Japanese, first appearing in 762 CE.[1] Cognate with 墨 (sumi, “ink; India ink”).[2]

In turn, from Proto-Japonic *sumi. Cognate with Miyako 炭 (sïm), Okinawan 炭 (shimi), Yaeyama 炭 (sïn).

Possibly derived from the homophonous 連用形 (ren'yōkei, “continuative or stem form”) 済み (sumi) of verb 済む (sumu, “to finish, to conclude”), from the way that cinders are left after a fire has finished burning.

Possibly also related to 煤 (susu, “soot”).

1. ink
2. (specifically) India ink

1. stem or continuative form of すむ (sumu) [godan]

1. a surname

From 酸 (su, the stem of adjective 酸い (sui, “sour”)) +‎ み (-mi, “-ness”, specifically for subjective impressions).[8] The use of the 味 kanji is an example of ateji (当て字), in this case, phonosemantic matching with a possible conflation of senses.[9]
