|day; sky; heaven||(surname)|
|simp. and trad.
First recorded use in the Traditions of the Western Regions (西域傳) portion of the Book of Han, finished in 111 CE. Itself a transcription of Old Persian *Hind-uka - hypocoristic of *Hinduš ("people living beyond the Indus").
- 身毒 (Juāndú)
|Kanji in this term|
/tendiku/ → /tenziku/
- Old Persian *Hind-uka, an alternate of *Hinduš (“people living beyond the Indus”)
- Sanskrit सिन्धु (Sindhu, “the country around the Indus river: India”)
The prefix senses appear to have arisen after European traders arrived in Japan, by way of India.
By extension from the 天 character (“sky, heavens”), and possibly by association with the Himalayas.
