Synonyms in other languages include Khmer tep (ទេព) or preah (ព្រះ), Tibetan lha, Mongolian tenger (тэнгэр), Chinese tiān (天）, Korean cheon, Japanese ten, Vietnamese thiên. The concept of devas was adopted in Japan partly because of the similarity with the Shinto's concept of kami. Other words used in Buddhist texts to refer to similar supernatural beings are devatā "deity" and devaputra (Pāli: devaputta) "son of the gods". It is unclear what the distinction between these terms is.
