  • flat (heiban)

How to read it: a line over a kana means the voice is high there, and ↓ marks where it drops. A kana with no line is low. With no ↓ the pitch stays high to the end and does not drop even on a following particle (が, は).

Select a part to see every word so far that is taken apart with it.

Wiktionary's text doesn't split this word, so each part is one of its kanji (with the okurigana written after it), with the reading and the dictionary meaning KANJIDIC2 gives that character — a word doesn't always use every sense of its kanji.

What Wiktionary says

Quoted line by line from Wiktionary's Etymology section for this reading, taken from one dated dump so it can't change underneath us. Nothing below is paraphrased.

Not settled

Wiktionary itself hedges on part of this word's origin — those lines are marked below.

  • “Japanese sources consistently describe the abacus itself as being imported to Japan from China some time during the Muromachi period (1336–1573), although there is some disagreement as to whether this happened early in the period, or late.”
  • “First attested with the reading soroban in the 1595 trilingual Latin-Portuguese-Japanese dictionary Dictionarium Latino Lusitanicum, Ac Iaponicum, also 羅葡日対訳辞書 (Ra-Ho-Nichi Taiyaku Jisho, “Latin-Portuguese-Japanese Translation Dictionary”) based on work originally by Ambrogio Calepino, corroborated in the Nippo Jisho of 1603.”
  • “Japanese sources generally describe the soroban reading as a shift or corruption from the reading swanpan, the 唐音 (tōon, literally "Tang sound", referring to the Chinese-derived kanji readings that were borrowed into Japanese during the Tang dynasty or later) for the kanji spelling. However, this is problematic on phonological grounds:”
  • “* There is no known phonological process whereby swan would become soro in Japanese.”
  • “* Middle Chinese swan consistently became Japanese san in all other known instances of the Chinese reading swan for any kanji character.”
  • “* The character 算 appearing as the first character in 算盤 (soroban) is also read as san, and san is similarly listed as a synonym for soroban in the 1595 dictionary entry.”
  • Hedged“An alternative, albeit speculative, explanation is that this soro- is some other morpheme unrelated to the Chinese. If so, this might be native root soro-, as seen in adverb そろそろ (sorosoro, “quietly and calmly”), そろり (sorori) and そろっと (sorotto, “quietly and smoothly; slidingly, glidingly”), verb 揃う (sorou, “to be in alignment; to be in order; to match, to go together”).”
  • Hedged“Notably, this term appears historically with the alternative kanji spelling 三羅盤. Given the expected Japanese readings of these characters, this may have been read as saraban. Root sara- -- and also root suru- -- also appear in various terms related to senses of smooth, gliding, sliding.”
