Proto-Ryukyuan

Etymology

According to Kupchik (2021), borrowed from Amis cidal (“sun”).

Alternatively, ultimately from a source deriving from Chinese 天道. Proponents of the Chinese derivation use other examples where Sino-Japanese au correspond to Proto-Ryukyuan *-a(a); e.g. *sata (“sugar”), *katya (“mosquito net”), etc. Hattori (2018, 67) also cites Old Okinawan correspondances in the Omoro Sōshi, such as すぢや (suj(iy)a, “all living things”, 素性 (sujō)), ひやし (h(i)yashi, “rhythm”, 拍子 (hyōshi)), や (ya, “look, appearance, way”, 様 (yō)), きや (k(i)ya, “capital”, 京 (kyō)), いちらご (ichirago, “Ichirō”, 一郎子 (Ichirō-go)), たら (tara, “Tarō”, 太郎 (Tarō)). However there are problems:

• *sata (“sugar”) has word-final length, which could imply the diminutive suffix *-a(a).
• *katya (“mosquito net”) is strangely absent from all Amami dialects except for Toku-no-Shima and Yoron, where it instead uses *kaya, but it is attested in Okinawa, Miyako, and Yaeyama topolects, implying a loanword from a Chinese source in (Proto-)Okinawan with a spread to the south.

The word *pi refers to days; this word likely displaced this meaning due to a taboo homonym *pi (“vulva”).
