す

Derived in the Heian period from writing the man'yōgana kanji 寸 in the cursive sōsho style.

• IPA^(key): [sɨ]

• During the period from Old through Early Middle Japanese, the pronunciation may have ranged between /su/ and /ɕu/. There are some man'yōgana spellings that use 周, deriving from Middle Chinese 周 (MC tsyuw).

す • (su) 

1. The hiragana syllable す (su). Its equivalent in katakana is ス (su). It is the thirteenth syllable in the gojūon order; its position is さ行う段 (sa-gyō u-dan, “row sa, section u”).

• ず (zu)

From Old Japanese. Found in the Kojiki of 712,^[1] and included in the Man'yōshū with the phonetic man'yōgana spelling 須 (su).^[2] In turn, from Proto-Japonic *su.

   • c. 759, Man’yōshū, book 5, poem 892:

     可麻度柔播(かまどには)／火氣布伎多弖受(かきふきたてず)／許之伎尓波(こしきには)／久毛能(くもの)須(す)可伎弖(かきて)... [Man'yōgana]

     竃(かまど)には／火気(かき)吹(ふ)き立(た)てず／甑(こしき)には／蜘蛛(くも)の巣(す)かきて... [Modern spelling]

     kamado ni pa / kaki pukitatezu / kosiki ni pa / kumo no su kakite...

     without blowing on the embers in the woodstove, and with cobwebs in the steamer...

From Old Japanese, from Proto-Japonic *su. Ultimate derivation uncertain.

• Perhaps a native Japanese term, with the su reading somehow related to the way that very sour things cause one to pucker.
• Alternatively, from Middle Chinese 醋 (MC tshuH). Borrowed earlier (vinegar was historically introduced to Japan in the 300-400s from China) than the systematic introduction of kanji, thus later mistaken as a native Japanese term. Compare modern Mandarin 醋 (cù) or Cantonese 醋 (cou³).
