This work is a rare specimen of Uzbek scientific prose of the XY century. The author compares the Turkic language with Persian in the play and points out that the word "lament" has a hundred synonyms in the Turkish language, emphasizing that the Persians pronounce this word with only one (Greek) word. The author also emphasizes the peculiarities of the Turkish language in the field of word formation and vocabulary. Although the title of the work means "Discussion of Two Languages", so far it has been written in two versions: "Muhokamat ul-lug'atayn" (pp. 4-28) and "Muhokamatu-l-lug'atain".

The phonetic, morphological and syntactic features of this work have been studied and are being studied by Uzbek scientists from various scientific points of view. This work belongs to such disciplines as "Uzbek dialectology", "Historical dialectology". In this play, Alisher Navoi is approached both as a creator and as a scientist. In these and other works of the poet, one can feel the presence of a name, a title, a figurative (metaphorical) name and a serious approach to it. This work has been scientifically studied many times, and it can be studied even more specifically in the development of linguistics. After all, if a poet is glorified by his people and language, he will never fall below the rank of a great poet and scientist.

So, it was specific to the period of the Soviets that Russian and international words came to our language. That’s why in this period singarmonism was ignored in the books on linguistics and in the lessons of the higher education of the republic. But this remained in the dialects of our native language.

This kind of naming was often discussed in the scientific books of 40s of 20th century and up to now praicing the poet.
