断么九

• 断么(タンヤオ) (tan'yao)

Probably from 断(タン) (tan, “sever, cut off”) + 么(ヤオ)九(チュー)牌(パイ) (yaochūpai, “terminal and honour tiles”). (Can this⁽⁺⁾ etymology be sourced?)

The pronunciation is borrowed from Mandarin 斷幺九 / 断幺九 (duànyāojiǔ).

• IPA^(key): [tã̠ɰ̃ja̠o̞t͡ɕɨː]

断么九(タンヤオチュー) or 断么九(タンヤオチュウ) • (tan'yaochū) 

1. (mahjong) all simples: a 役 (yaku, “hand”) that has 2-8 of any of the three main suits, lacking any 么九牌 (yaochūpai, “terminal and honour tiles”), worth 1 翻 (han, “double”)

• 喰(く)い断(タン) (kuitan, “open tan'yao”)
• 中(チュン)張(チャン)牌(パイ) (chunchanpai, “suited tiles numbered 2-8”)
