す

Japanese

Stroke order

Etymology 1

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

Pronunciation

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).

Syllable

す • (su)

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”).

Derived terms

Etymology 3

Alternative spellings
酢醋酸

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).
