Proto-Ryukyuan

Reconstruction

Deletion of the second syllable in some Amami dialects and the Miyako forms point to *tukur-. Yaeyama and Yonaguni forms point to *tukor-, but there is no case of **tuku- changing to *tsïfu ~ *ffu in any Yaeyama dialect.

There is also Okinawan しこーゆん (shikōyun), attested in the Nantō Kayō, and Sanuki しこー (shikō, “method”).

Etymology

From Proto-Japonic *tukur- (“to make”).
