Yin Collection, Middle Volume Radical: Mountain (shān) Island. Kangxi strokes: 10. Page 312, Entry 01 Pronounced dǎo (falling-rising tone). Shuowen Jiezi (Shuowen): A place in the sea where there are often mountains that can be relied upon for support is called an island. Derived from mountain, with niǎo (bird) providing the sound. Shiming (Explanation of Names): An island is a place one arrives at. It is a place where people rush to arrive. Book of Documents (Shangshu), Tribute of Yu (Yugong): The island barbarians wore clothing made of skins. Kong's commentary states that sea bends are called islands. The barbarians who reside on these islands return [tribute] wearing their skins. Mu Hua, Sea Rhapsody (Haifu): Lofty islands and giant sea turtles. Also, according to Jiyun (Rhyme Collection), it is sometimes written as the variant form (dǎo). Zhang Heng, Rhapsody on the Western Capital (Xijing fu): Long winds surge at the separate islands. Also written as the variant form (dǎo). According to Jiyun, it was historically used interchangeably with the character for bird (niǎo). The character is derived from mountain, with niǎo (bird) providing the sound. Textual verification: Shuowen Jiezi (Shuowen) states that a place in the sea where there are mountains that can be relied upon for support is called an island. Island means to arrive, a place where people rush to arrive. Derived from mountain, with the bird radical simplified providing the sound. Book of Documents (Shangshu), Tribute of Yu (Yugong) mentions the island barbarians wearing herbal clothing. The commentary notes that sea bends are called islands, and herbal clothing refers to items such as cotton that were brought as tribute. I note that the cited text does not match the original. I have corrected it according to the original text of each book: Shuowen Jiezi (Shuowen) states that a place in the sea where there are often mountains that can be relied upon for support is called an island. Derived from mountain, with niǎo (bird) providing the sound. Shiming (Explanation of Names) states that an island is a place one arrives at, a place where people rush to arrive. Book of Documents (Shangshu), Tribute of Yu (Yugong) mentions the island barbarians wearing skins. Kong's commentary states that sea bends are called islands. The barbarians who reside on these islands return [tribute] wearing their skins. Mu Hua, Sea Rhapsody (Haifu) mentions lofty islands and giant sea turtles. I note that the character for sea turtle is written with the component for reptile, not fish. I have corrected it to the original text of the Sea Rhapsody.
