Conjunction wja1 in Tangut Language

Abstract Tangut wja1 is considered as a verb, a noun or a pronoun, which is ambiguous in current dictionaries. This paper makes it clear that wja1 is a conjunction in grammatical words of the Tangut language, and can be used to translate the conjunction na in Tibetan language. This conjunction usually occurs at the end of a former clause in a compound sentence, and expresses progressive, hypothetical, conditional and sequenced relations with the latter clause. Moreover, the latter clause is usually an interrogative sentence, in which there are mostly rhetorical questions in the progressive relation complex sentences, while it can be rhetorical questions or general questions in other complex sentences. However, there are some individual exceptions without using interrogative sentences
