If we investigate the trend of ambiguity in Persian poetry, Khaghani and Bedil will be among its peaks. The complexity of their poems has expanded the opportunity for different ideas about their poetry, to the extent that sometimes several opinions have been expressed about a single verse. This article aims to investigate the ambiguity in Khaghani and Bedil's poetry from two lexical and syntactic perspectives. At the lexical level, the use of old and underutilized words, the combination of words and the use of words and combinations of other sciences will be manifested, and at the syntactic level, things such as linguistic ambiguity, artistic ambiguity and ambiguity caused by incorrect textual criticism. The necessity of studying Khaghani and Bedil as two prominent poets of the Persian language shows the importance of this research. The research method is documentary and by using library facilities. The result of the research is the comparison of the types of ambiguity in Khaghani and Biddle's poetry through presenting charts.
